No, eight characters, some capital letters and numbers is not a good password policy

The other usability thing that is most often ignored is the ability to get special characters on mobile devices with pop up keyboards. At least 3 extra taps to a get % symbol and back to alpha, not to mention how bloody obvious that can be to someone peering over your shoulder.

Better late than never: nbn™ DOCSIS 3.1 upgrade starts

Concerned but optimistic

I got an unexpected upgrade to 5Mbps Uplink on my Telstra Cable a few months ago without changing anything at home. I suspect this is the prelude to the proper Docsis 3.1 Uplink lift to 20Mbs

Availability advice is unavailable

Perhaps with the issues is with Telstra's (and other telcos') time honoured availability process.

1. Definitive availability statements will be given in response to an actual order.

2. An actual order can only be placed for a premises, if you own, live or work there.

So how does someone considering a property get an unequivocal answer on availability?

You can't!

Apart from all that, the issue is caused by investment paralysis, induced by the prospect of NBN availability. That should not necessarily be blamed on NBN. It is short sightedness by suppliers who should know the likely roll out times and be happy to invest in order to service customers for 5 years.

Re thinking risk profiles

A good point is raised here in regard to the transaction integrity and retention capability of the DR site.

An often forgotten part of DR planning is the decision tree. A good decision tree will help evaluate the type of disaster or outage being faced and weigh the cost of enacting a particular course of action against another.

It may well be that the known costs and risks of migrating to (and back from) the DR site to live were estimated to be very high, and so additional time was invested in repairing the primary site. This does spell out a weakness in all but the most sophisticated (and expensive) DR strategies.

A lot of DR strategy testing/proving is focussed around reestablishing core capability in the event of critical failure or destruction of primary site. These are predicated on the magnitude of risk in wholesale damage and long term repair prospects at the primary site. Not enough work is done on coping with the lower magnitude of risk involved with various equipment failure and the relative costs of migration vs repair.

N+1 is fairly fundamental here. Switching to the DR site should not involve accepting subpar data protection or data integrity. Operations like these need two fully operational systems/sites with as close to realtime transaction mirroring as possible.
