US starts 'emergency' checks on cryptocurrency power use, citing winter power demands

@John Robson

That is one of the most lucid and considered replies in a while, and with sensible empirical evidence* actually referenced as well. Thank you very much for bothering.

'when the local grid isn't as strained'.....'but our current domestic usage is really peaky'

I can't help feeling that as the energy mix changes, all we'll do is to move the peaks in time and increase their magnitude - and therefore the point where the grid it strained - it will *always* be strained sometime.

OK, reading that linked doc, I agree the consumption has been dropping YOY - which is probably due to increasing efficiency/lower consumption of residential/domestic appliances and the switch from aged inefficient technology like tungsten filament lamps to comparatively efficient LED. Efficient in opex terms anyway - tungsten filament cost pennies to produce and could be bought retail cheaply. Capex-wise LED costs several £/$ more than filament lamps.

The difference between the power consumption of filament vs. fluorescent vs. LED is well known and the latest and greatest 'LED' is the winner, natch. However, if EVs are adopted/consumed at the rate expected (very fast!), the overall 'delta increase' will be far out-strip the 'delta decline' in consumption shown - which is at the 'macro' level.

My reasoning is based on the following : My commute to work : 4 Miles each way. By boss's commute : 40 miles each way, and his EV is charged at work, along with 1 other user. The charger available is 7.5KW, and they are BOTH plugged in, drawing ~30A for hours on end.

Leaving a 40W TF lamp on for 5Hrs=0.2KWh. Leaving a 4W LED on for 5H=.02KWh. Leaving a 2KW electric storage heater or convector heater on to 5Hrs=10KWh. Leaving an EV on for 5 Hrs=37.5KWh...and 5HRs for a moderately-discharged EV is a conservative figure....yes, these are 'micro' figures, but 'macro' is the sum of 'micro'....

We both know that the consumption curve can be smoothed out with some co-ordination and motivation - but people ('Consumers') are too selfish to do that without regulation and/or enforcement.

Nice riposte, but I remain unconvinced.

"push up people's bills"

It's not just a US problem. Electricity is in short supply. Even if you disagree with that due to the 'Renewable' green stuff like Solar/Wind coming on stream, you must agree that it's getting harder and harder to deliver the required increasing number of electrons using the 'Grid' - which most people still rely on.

The major problem is here is that the infrastructure has not kept up with the abrupt increase in demand....OK, the HV transmission system we call the Grid may be able to cope with the demand NOW, but as transport moves off fossil fuels onto 'leccy, we'll find out it's the aging HV-to-LV conversion equipment (Substations) and the LV distribution system (Underground/overhead cables and transformers etc.) are going to become the issue. That 'last mile' is a killer, just as it was for POTS and xDSL.

As the ratios of energy types we use becomes more biased towards electricity - and it will due to electric vehicles, heat pumps etc - we'll find that the seriously old LV distribution infrastructure we all use can't cope. Even if we *can* generate enough electricity to satisfy demand, I doubt we'll be able to get it to the point of consumption - you and I - where it's needed. Here in the UK, most LV distribution is underground in the metropolis, with overhead cabling being used in the more rural areas....but it's all very elderly and has a design capacity of way, way less then we think we're going to require.

As we change the ratio towards 'leccy, the 'Grid' and regional suppliers/LV distributors will be forced into upgrading their infrastructure to cope..... for which we will ALL have to pay as they won't do it out of altruism, at least not while there's shareholders to satisfy. In fact, looking at the UK MPAN, (See 'Loss Factor') we can see that we the distribution operators are *already* aware of how much it costs them to deliver our electrons. We get charged for the cost of delivering our consumption over the 'Grid' infrastructure, and IMHO this is why you always have to provide your MPAN when shopping around.

Bitcoin, and indeed *any* 'Proof of work' based cryptocurrency consumes a disproportionately large amount of leccy when you compare it to the 'average citizen' consumption. I don't see why I should be expected to pay more for my electricity usage to 'subsidise' some corporate entitiy's need to fund their increased delivery costs incurred due to someone else's desire to do the very, very electricity-intensive crypto mining malarkey - 'Proof of work' based or otherwise - or desire to charge their very hungry electric vehicle.

If ever there was a use case for 'Pay as you go' (Or 'pay as you consume', if you prefer) - electricity is it.

Here endeth this Vino Rosso induced rant.

Re: Bots, not bodies.

"With rare exception, a robot will outperform a human, probably by orders of magnitude."

Care to expand on the reasoning behind that?

If you'd written 'outperform a human at any given specific task' I'd agree with you, however, as you didn't here my take:-

I think you've got that arse-about-face...a robot that will outperform a human at *any* task is the exception case, as the robot must be programmed for said task in the first place. The robot who can *generally* outperform a human has yet to be born/created.

Oh yeah... AI can't do anything in the physical world without assistance, so it don't count.

Partial understanding is the norm

"You copied that function without understanding why it does what it does, and as a result your code IS GARBAGE."

I'm with Linus on this one. If there is one thing certain to get me annoyed it's having to clean up after someone who did something complex without understanding what they were fucking with*.

Even leaving aside the history, filesystems - even the comparatively simple 'basic' ones - are hard to understand at times. There is *always* merit in reading/learning about that you are about to start screwing with.

To me, this seems to be happening more and more. People seem to just be happy to learn how something works, but not why it works like that. Asking the 'why' question makes you a better engineer!

New year, new bug – rivalry between devs led to a deep-code disaster

Re: Test on the slowest box

As I've said before, I used to be professional tester which was enormous fun :-)

Along comes carrier-grade VOIP, and I managed to add an item of test equipment - the Shunra Storm - to the list of project test equipment. At the time, it was the newest and smartest bit of WAN simulation kit available, and allowed all-too-real simulation of WAN Link speed, insertion of jitter, packet duplication and and packet loss (in one or both directions) and other packet-related skullduggery. Sounds hard, but it was comparatively easy to describe the topology to emulate and the packet effect simulations to apply thanks to the then *very* innovative use of VISO as a front end to desribe the topology and desired packet effects.

I cannot over-estimate the importance and impact that device had....and all in a 2U little box. Beers & props to the developers.

Myself and my colleague were either loved or feared by the devs - loved for finding all sorts of 'retry' bugs with the packet loss tricks, and feared due to the latency tests which exposed one or two gaping holes! After a while, the call agent stopped falling over and started to become more resilient, handling some godawful network conditions without falling down in an irrecoverable heap!

If you worked on the XCD5000 and/or the NN 1460 SBC, then we probably know each other:-) Good times.

Re: Lychford Road

I can't name names here, but I can tell you that there are at least two utilitiy companies switching to/introducing metering over LoRA. There are a couple of networks building out infrastructure in targeted areas to accommodate this. It's a pretty good technology fit for metering, which is generally low bandwidth (comparatively tiny PDUs/packets of just a few bytes), sent very infrequently. LoRA is ideal for that sort of 'low rate telemetry' stuff. Considering the RF power used, the freqs used and the link budget available, the achievable ranges are ... Very impressive!

Re: Going to be awkward

The difference in 'nG' is largely due to the changes/improvements in the RF side of things which allow you to squeeze more 'bits' into any given amount of spectrum/bandwidth. The more 'bits/Hz' you get, the faster things can go.

Improvements in RF transceiver technology have largely driven this, as they enable the use of more complex modulation schemes that carry more bits/Hz than before, whilst increasing the resistance to RF effects like multipath fading etc. If you fancy a headache, go read up on OFDM and QAM.

The reason for going ever upwards in frequency is that the higher you go, the more spectrum bandwidth - and therefore bits/Hz - is available. However, higher freqs run out of puff faster (AKA propogate worse) than lower ones, which is why you need a higher number of cells to give useable RF performance to a given geographical area, even with sectorised antennas and the really funky beam steering going on. Don't forget this works two ways - handset to cell and cell to handset. This all adds up to more capex for the operators, which is why...

We lost some terrestrial TV spectrum a while back so the operators could have access to more (comparatively) low freq/longer range spectrum to play with. 2G and 3G are elderly now and inhabit the lower parts of the spectrum available for mobile/cellular services....and are probably on the chopping block so that their valuable spectrum can be (re-)used for the more spectrally efficient and resilient newer 'G'enerations.

RF spectrum is in short supply and already congested. If you want to know how awkward this can get - in the UK at least - go have a look at the Ofcom spectrum interactive map. You've got to love this RF stuff. It's another example of a very analogue lower layer carrying the Digital World on it's back. Never doubt that analogue rules the roost!

Apple's quest for modem independence from Qualcomm is going nowhere fast

vogon00

@Groo:Spot on.

If you look at things in block diagram form, it does indeed look simple. It's not until you start monkeying around with RF at the necessary frequencies, bits/Hz, modulations, levels of miniaturisation and so on do you realise the scale of the mountain you are trying to climb. It's a very complicated thing to try, and IMHO requires a more analogue skill-set than digital. Those skills are hard to find.

And they haven't even got to arguably the most challenging and important part - the antenna array. LTE is well understood and mature now, but 5G-SA involves a new set of rules for the sub-6GHz bands, especially keeping the power consumption within sane limits.

A lot of the day-to-day task automation we use in our SMB depends on a library (or 'toolbox' if you want) of VBScript procedures which gets referred to as 'The Engine', as it's this that drives most of the common tasks, especially those executed frequently.

The benefit of VBS is that it runs on any machine in our workplace, and is easily understandable by people with different skill levels, the latter being good as it's served as a springboard for noobs to stop being scared of 'coding' and get interested. One of our best devs started out this way.

Looks like VBS is now the 'old fossil fuel' and PS is the 'new electric'. Here's hoping VBA is next on the block:-)

Can't wait for more concrete information on the actual sunset date, as this will hopefully provide an acceptable justification to start doing things a more sustainable way.

Re: don't forget

"Abhorrent mess, bring back the engineers."

Just that[1].

A couple of years ago, I was asked to 'integrate' a bit of 24VDC industrial kit. No suitable bench supply was available (All in use), so I convinced the boss to buy one for the job - justifying it as 'Needed immediately' and 'Customer/Project funded', plus it would be useful later on, as our own products were evolving in that direction.

I specced up a reasonable bench PSU (0-50V, I forget how many amps), and found something sort-of-reputable online for what I felt was a reasonable amount of money - after doing the 'is that too much' risk-vs-reward due diligence beforehand, including some justification text, exact model number and vendor. ISTR it came to somewhere around GBP250.

The next day, a PSU arrived. Not *THE* PSU, just 'A' PSU, which was the cheapest piece of crap available on flea-bay. 4mm binding posts that wouldn't accept any of the 4mm 'Banana' plugs in the lab, one segment of the LED display stubbornly remaining unlit, and the V and I pots wobbling all over the place...not to mention an *audiable* inductor.. Definitely sourced from flea-bay, as that's what the invoice/receipt inside the (damp) box said, and the receipted price was GBP60. Being curious, I put the output on a 'scope and was shocked at the shitty noise present (And I've seen loads of 'iffy' PSU outputs before). It seems my purchase request got 'edited' by manglement:-) I bitched, got told to make do.

48 hrs later (mainly PSU drying time), I had things working and went to get a coffee. I came back into the lab and my colleague said they turned the bench off due to smoke coming from what I was working on. It turns out that that the shitty PSU lost output voltage control, and shoved 60VDC at something nominally 24VDC and with an abs-max of 40V, thus killing it. This 'something' cost EU720.

Told the Boss (The editor!) and got the 'What did you do to it?' question. My response was considered, but that's the closet I've ever come to using verbal or physical violence on a colleague! I still can't forget that one.

Chemisty is not my strong suit....

...but after dredging up something hammered into my thick grey matter by the excellent Dr. Mike Bee (At THS), something doesn't read quite right to me...

OK, Carbon Dioxide is CO2, and the article says "an electrochemical process in which one oxygen atom is extracted from each carbon dioxide molecule" is used (My emphasis).

If I understand things correctly :-

[a] After 'cracking' the CO2, that leaves you with a molecule of CO and one atom of oxygen, AKA 'Elemental Oxygen'.

[b] What we want is good old O2, meaning a molecule of Oxygen rather than just a single atom of the stuff.

Now given that "NASA noted that the most important use of oxygen", doesn't that suggest there has to be a process for combining the single atoms of Oxygen extracted into actually-useful O2 molecules that we want ( And presumably *NOT* Ozone/ Trioxygen / O3 or tetraoxygen / O4 )?

Why not 'Crack' out and discard the C/Carbon leaving the O2...or have I missed something? Chemists, please educate me:-)

Re: VOIP vs POTS

I spent a lot of my career with all sorts of different parts of System-X over the years, from the 'edge' at the concentrator / DSSS that your 2W line terminates at, all the way to the processor at the 'middle' (Both the 3.5MWord and 28MWord versions), with a few stops at DSS on the way. My initial involvement was repair of faulty slide-in-units to component level (Anyone else remember ED0618 and PSC-South), then into 'System Proving' (QA/Testing) of every facet of the thing....hardware, software, you name it, we tested it :-) I dunno about the others (Under the guidance of DickMon), but I had real fun and learnt an absolute shit-tonne of stuff which still stands me in good stead today...I was taught my hardware, firmware, software, 'testing' and systems engineering by my peers and a bunch of shit-hot developers of the same - no degree necessary :-) Some of the people I knocked around with were seriously smart [I am merely very smart :-].

The Proving teams later morphed into the 'core' of the integration function for a whole load of emerging technology - SDH, Kilostream (Old by then) and the management thereof. VOIP and DSL came along and we had a thoroughly fun and challenging time getting to grips with the new-fangled packetised speech and signalling protocols. In many cases, it was us 'Integrator' types who came up with test tools and/or simulations leading to *us* developing the fix rather than the devs.

I had the most fun in the whacky world of System Design, which is where I finished when E/// closed the site at Ansty Park in Coventry. By this time System-X was - and still is - cared for by Telent.

I can confirm that it was indeed "engineered" to very high standards, which arose because the people involved were professional and gave a toss about their product. I cannot over-emphasize the professionalism of the engineering teams involved, the attention to detail and drive to do a good job. Our definition of a good job was usually doing something that Joe Public never even noticed happening.

UK government hands CityFibre £318M for rural broadband builds

vogon00

Keep some of the money back for 'repairs'.

This story on CityFibre gives me a timely opportunity to have a minor moan. I was visiting friends yesterday, who live in a Vermin Media service area and....for some reason, actually take VM's service.

Along their road, the buried VM cables transit the 'inside edge' of the pavement, before turning circa 90 degrees 'inwards' towards the properties using a 'CATV' marked box in the ground. From this, it then runs under a few feet of grass verge before reaching the boundary - in this case a wall.

CityFibre's local contractors (Not sure who is it round here, although I think it's Telec Networks) are in the process of running in infrastructure for real FTTP all over the place, and in this location appear to be using some sort of trenching machine. Now, CF are running their fibre/ducting along the boundary line. In the case of my friends and their immediate neighbor, they managed to shove the trenching machine through the buried VM Cables. My friend's drop cable was taped up and lightly buried suggesting 'no problem here, Guv.', but the neighbors cable had been ripped right out of the ground with such force that the coax had been stretched and pulled out of the buried connector. It's not particularly weedey coax either - something along the lines of RG213/URM67/LMR400 (OK, it's not armored or LDFxxx, but pretty tough normally).

Fairly recently, the VM phone service changed from analog POTS via a 2W pair/Co-Ax 'Hybrid' drop to VOIP only, with the VM Set-top-box providing telephone service inside the house using an internal VoIP-FXS adapter.

Result:Neither Internet OR 'phone service at each property. My friend and I 'bodged' service back into place with some scrap co-ax and tape, mainly as the elderly-ish neighbors were very anxious about the no 'phone service part.. I don't *know* how many other properties along the road were affected, but my guess is quite a few (The contractor's people obviously didn't learn from the 1st mistake!).

Dear CityFibre, please keep some of this 318 Mil back to fix the eff-ups of your contractors, or at least fund the efforts to chase them into fixing the issues caused..

Do I feel sorry for Vermin Media in this instance? Almost.

Re: With two-faced "friends" like Dyson, Britain doesn't need enemies

'Henry' vacs etc have been a staple here in the UK for years.

My personal preference these days is for a vacuum cleaner that works for me - which modern Dysons do not. Not enough grunt, plastic parts wear out, batteries or other electrical bits fail way too soon to suit *this* director's[1] depreciation policy.

My personal favorite now that Vorwerk have lost the plot a bit is for a corded and bagged Miele, with the air-driven brush head (the air-driven head is mandatory - that's what turns it from average to brilliant). Far less faff than a Dyson and spares/bags/filers etc. are cheap as chips/fries if you look in the right places. I have a 'Cat & Dog TT 2000' model that is well over a decade old (maybe 15 YO?) and is still going strong.

Recently bought a more modern one for my elderly mother....she loves the result as it brings up the pile on the equally elderly carpet :-)

Whilst we're on about products like that, I was told by a very senior colleague a while back that he once sold a product to remove water/condensate from snowmobile fuel tanks.. drop one in the fuel tank and it 'vacuumed' up (absorbed, actually) the water at the bottom of the tank, thus avoiding a common cause of snowmobile failures out in the wilds where people depended on them. The marketing tagline for it was 'This product sucks!'. I don't 'do' marketing, but I thought that was quite a good line.

These don't generally matter to me as they are the English Subtitles over English audio, and I can spot the speech-to-text mistakes and adjust accordingly. However, the written word on it's own would have led to ...confusion. Some of the 'hiccups' don't matter, but some do - there have been a couple I saw that meant the written was most definitely NOT what was spoken. Sorry, I can't quote refs...it was quite a while ago.

Leaving aside the obvious mistakes/wrong words in the machine translation, what about punctuation? A 'Let's eat, Grandpa! vs. Let's eat Grandpa!' issue could be quite serious in the medical world.....and the legal come to think of it.

Also, the NLP/speech-to-text has problems with accents.... Sure, en-something may be the language, but any accent can confuse the beast, it seems - the more pronounced the accent, the higher the error rate. And that's with 'broadcast-quality' or decent audio input, not the muffled low quality crap you're likely to get as source from whatever low-tech, cheap, shit device is used to record the audio in the first place.

Until the 'error-rate' improves, especially with accented speech or a non-native speaker (in ANY language), I for one dread my medical records getting transcribed by AI. This seems like a baaaaaddddddd idea and pretty shitty science, 'pushed' in the name of progress,

Yup, NOT a fan of 'AI', because - just like Tesla's Autopilot - it claims to be something it ain't.

Humanoid robot takes a retail job, but not one any store clerk wants to do

Job theives?

The idea that robots will replace human workers on cost grounds is not, IMHO, realistic. Even if the robot worker can be as flexible as a human counterpart, what on earth makes people expect them to be cheaper? Capex / opex on an expensive bit of kit like a general purpose robot will likely far exceed the cost of a, possibly several, human worker(s). Good luck with that.

I'm all for progress and R&D, but I find myself wondering about the point of some of the innovative projects reported on here, especially the AI bullshit.

Re: FSD - No chance

"It's not just Teslas that can't read road signs correctly"

Boss has a full-EV Kia of some description, which apparently also reads speed limit signs. His commute starts in an area with several and frequent speed limit changes, with the 'slowdowns' to 30MPH. Boss also transits a couple of long-ish road segments where there are 'repeater' signs* reminding you the limit here is 40 or 50 MPH as the case may be.

If I wasn't such an honest mug, I would have been out-and-about with some paint, changing the '30's to '80's** and each 'repeater' sign to '10' then '90' alternately. Would produce an interesting commute, and be a good test of the machine vision...

Some more than others. It depends how much situational awareness you can maintain, and how much you trust your fellow road users to keep to the generally accepted norms.....whatever they are. Me, I assume that all road users, including myself, are human and fallible and allow plenty of space (actually thinking-and-action time).

Yep, that's all true. We never use the lessons of history, preferring instead to optimistically assume we can repeat the experiments of the past and get a different outcome.

Victims of IT scandal in UK postal service will get fresh compensation

vogon00

The heads that roll..

...will inevitably be the wrong ones, and will most likely to be the heads of the UK General Public - because we'll end up footing the bill somehow.

I have no problem with the victims of this awful scandal being compensated, preferable *hugely*, for what they went through and suffered. What I do have a problem with is the lack of any punishment for the people in command* of the PO/Fujitsu whilst this was being perpetrated. It sends the message that corporate culture *CAN* do what it wants with no comebacks. IMO, the people who were in command, especially those who advocated continuing along the prosecution route once 'reasonable doubt' had clearly been established, need to be the ones providing the compensation (Not the taxpayer) or receiving substantial punishment themselves. Fine the fuckers, fine them hard, and fine them publicly, ensuring *they* bear the legal costs**. Anyone at senior manager level and especially above needs a financial shagging personally without the benefit of Director's Liability insurance. I hope the outcome of the investigation is that the PO people responsible are identified and judged to have acted criminally (Which I think is enough to 'void' their directors insurance, right?) and thus open the route to 'criminal bankruptcy' and seizure of personal assets.

That's the dream, anyway...I doubt anything like the above, or indeed any punishment of the people responsible at all, will actually happen. Oh yeah - stop calling it an 'IT scandal' - it's not an IT issue. I.T was the cause, but the scandal was all human-led/driven.

* There is a difference between being in 'command' and being in 'control' - they are two very different things which should be drummed into ANYONE undertaking a business qualification.

** Or at least ensure the costs of the case aren't borne by the people supposedly receiving the compo - they should be receiving everything awarded to them without tax, and without having to pay the 'legal levy'.

Rant ends. I hope the inquiry does identify the culprits and bar them from any further corporate activity, the bunch of cunts...

'American beer is nothing more than fizzy piss'

Some time ago, I was in Duluth, just outside Atlanta and was having a 'Saturday night session' at the local bar. Being on a budget, we were drinking the 'Draft Bud', and put away quite a bit of it, during a very enjoyable evening.

Paid for it the next day by feeling truly awful....banging headaches, aching body and limbs despite drinking about two pints of water before sleepies to ward of the dehydration. Never in my life had I, not have I since, I suffered like at the hands of the demon drink. Don't normally get hangovers, but that one put me flat on my back for most of Sunday.

Draft beer? More like toxicity-on-tap! Didn't stop us re-visiting the local bar...we just drank something else...mostly Michelob, ISTR. Barkeep there must have overhead the whinging we were doing as some 'craft' beers arrived a couple of weeks later and were enjoyed by us Brits and our "127's" (The 'localhosts').

Re: FFS

'it will actually get better and better and learn'

Yes it will, but only for as long as humans are the ones doing the learning and expressing their knowledge and experience in the code. Even then, unless there is continuous transfer of knowledge and experience from the outgoing 'old guard' maintainers to the incoming 'new guys' us humans will forget *why* that bit of code does what it does in the wider system.

Given the propensity for people to just have a go despite not understanding what they are about to do, IMO there has to be an assurance that the overall system and code-base are continuously, and thoroughly, understood despite the inevitable staff/dev turnover.

AI is NOT the answer. AI is not, and never will be, capable of dealing with the 'edge cases' as they arise - you've only got to watch a few Mentour videos (Other providers are available, including CAA/FAA/NTSB 'wash ups') to realise that issues generally get solved by humans, not machines.

If something has gone wrong, that's where I want a properly qualified pilot with some experience in charge. Also, two real pilots instead of one mean there are two heads involved, and there is the chance to talk something through with a peer, or at least someone different, first. The only thing AI has to converse with before taking action is...itself..or more correctly the programmer who created it, or the crap data it was trained on.

If the stories about 'Olympic Airways 411' are true, the only thing that stopped a disaster was a bloke with experience - something that AI, and it's coders, cannot have (Especially as the human through the rules book out of the window..which AI would never consider doing!)

When it comes to flying lots of people about, the best things to oversee that activity are other humans... assisted by automation, yes...replaced by it, no.

OK, I guess supply/demand/costs will win and either single-or-zero pilot air travel will happen. When it does, I hope the CEOs of the airline and/or of the company doing the flight control software are forced to be on the certification flights and 'eat their own dog food'.

Massive energy storage system goes online in UK

vogon00

Re: it can only take the output of about 15 Dogger Bank turbines

"Looks like you'll need about another 200+"

If I read this correctly, you're saying we need to build 200 more of these here to store the output of 'Dogger Bank' as a whole.

We appear to be talking about 196MW of storage per multi-unit site...so say 200MW, for a few percent of the peak load period Each 200MW site appears to be able to store and supply (later!) circa 92-94-% of one fifth of the older '1GWe' 'power stations' or one fifteenth of a modern (i.e. nuclear fission) UK electricity generation facility at about 3GWe.

One can't store something unless it is generated in the first place. The last thing we need at the moment is a large increase in load (1000s of electric vehicles @ e.g 15KW/h) combined with more bias towards electricity as natural gas becomes rarer/more expensive*) at the same time we're loosing generation capacity.

So call me back when there is something to replace the short, medium and long term loss in generation capacity we face due to eliminating fossil fuels and decommissioning the 'nuclear fleet', combined with the increasing loads involved with everyone plugging in their EVs etc...

* I have two elderly relatives who are already switching to electric fan-assisted convection heaters or plain old 'fan heaters' used in one room only to avoid heating the rest of the house. I know of at least one family-of-four who use a 10KW electric shower in an attempt to keep the gas bill down (Without doing anything about the overall energy bill - talk about 'Borrowing from Peter to pay Paul'!).

Mine's the one with the extra-heavy-duty thermal insulation.

tsoHost pulls plug on Gridhost service with just 45 days' notice

vogon00

tsoHost ain't what it used to be.

It used to be pretty good back in the day but has steadily deteriorated over the course of several years.

Yes, we had issues and outages but they were never that serious (Apart from them upgrading PHP and not letting us know, and the great 'Domains beginning with B' débâcle which hit us). Also we were on a shared hosting machine (Probably their cheapest, knowing our bean-counters), and I had to keep saying to the MD 'You get what you pay for'.

Like a lot of people, we got caught out by this Gridhost turnoff, and spent about two days with no web presence at all, then another 2 or 3 days with a holding 'Sorry, we've got problems' page before the brand new shiny website we had waiting in the wings came into service....much to the relief of our worldwide customers, some of whom thought we'd ceased trading or something.

We were lucky with the new site. All we had to do with this was advance our plans by a couple of weeks. I know of various colleagues and contacts that have anywhere from 40-odd to 162 sites affected. All of them swear they did not get a single warning email in their working and monitored mailboxes that were registered with tsoHost.

The MD and I have spent the last couple of days updating content and sorting out all the redirected domains and email etc. It's been a bit of a panic, but no too bad as these things go.

People are right about the poor support at tsoHost. The chat que lengths were horrid. We always started out as #160-odd in the que, and it took hours to get to the top. Then you get a canned stock answer, and back you go to the bottom of the que. Actual support tickets were a bit better, but not much. Once we had persuaded them to re-instate FTP access for backing up (Which they managed to get working on the 3rd attempt), we said 'F This' and committed to moving away from them as fast as possible...it was sheer luck we had a replacement site nearly ready to go, with another provider. Professional companies who see support as an obligation rather than a cost centre generally put extra resources in place just in case - especially on and after the 'due date' - something this bunch of tossers didn't.

Had they actually warned us, or any of our colleages/contacts, we would have known in advance and could have dealt with the turnoff more efficiently instead of this un-planned 'sprint'.,.

tsoHost were on our our naughty step anyway (Hence the new site being on another provider), but we've added GoDaddy (And any subsidiaries) to the non-preferred/avoid vendor list now because we don't want the risk any more. Considering GoDaddy are US based where customer service is king, they've really dropped a bollock, service-wise. Not impressed.

tsoHost ain't the only one. We buy hosted exchange from giacom via a reseller, and for the last week or have had out outlook clients frequently asking for the password to {random mailbox}. We bitch at the reseller, they say it's a giacomp issue and are continually chasing them. I'm too far away from this to be sure, but it looks like giacom's authentication synch/replication across their server suite has issues.... Still ongoing with no sign of a 'cure' yet.

Overall, it's been a pretty shitty few days. Still, Vino Rosso helps..
