back to article Vodafone keels over, cutting off millions of mobile and broadband customers

Vodafone fell over in the UK this afternoon, with Register readers reporting that many services including mobile coverage, internet services, and even the company's own status page went down. The outage began on Monday at 14.25 BST, and 30 minutes later it peaked when monitoring website Downdetector.co.uk reported that almost …

          Up until earlier this year the communal washing machine and tumble drier in this block of flats ran off 20 rappen coins in a meter like that. It was 100% reliable.

          Our landlord replaced it with a card-based system that seems to die often and often won't read the cards...

            20 rappen? That's Swiss, isn't it?

            The Swiss had one of the most clever tricks I have seen with coins ever: their 50 'cents' (aka rappen) coin was very small (much smaller than the rest), so it was perfectly suitable for parking meters and stuff - a meter could hold a load before they were full up. Smart.

        One year ago I stayed in a Devon AIrbnb that had a thatched roof, an exactly 6 foot high lounge ceiling, fibre to the premises internet... and a coin slot electricity meter! Actually as it was summer a few £ coins lasted quite well for hot water and a bit of cooking. Perhaps the owner of the place was keeping that antique mechanical slot meter - 40 years old at least - as a character feature.

        My coin op bedsit of yore took 5p coins not 50p. And I found the landlady was overcharging, she had to have the meter readjusted.

    Where's the redundancy?

    OK, both their mobile and broadband networks went down at the same time suggesting shared infrastructure, OK their status page went down as it's probably connected into the back end, OK their web site went down later probably due to load, OK their phone lines went down as they're probably using VoIP by now, OK their social media team went down as they're probably on the same network and no one is allowed to use another device or whatever... OK it seems to have affected other countries and networks as they share infrastructure, OK people that pay for a backup line got nothing as it's the same back end, OK their press comms was extremely basic and uninformative as the key people were probably too busy to send out clear messages.. but... why do they seem to have single point of failure affecting the whole country?

      I think you'll struggle to find a public or private system that doesn't have *some* level of SPOF within it. It might be known about, it might not, but it'll exist. As you'll see from many comments in here, people may well have had "backups", but if they unwittingly shared Voda infrastructure, that too is a SPOF.

      And there's not much to protect yourself around a botched BGP update.

      If you work in IT, the redundancy is in your dual SIM phone. Just as you'll have two credit cards with (genuinely) different banks using different payment card service providers and cash in your wallet. And you have mobile internet ready to go when your fibre connection fails. And you have a second favourite pub for when your first choice unexpectedly goes out of business.

        Yup - as soon as I realised that my Vodafone broadband and Vodafone primary SIM were borked, I switched my phone over to my Tesco Mobile (O2) backup SIM and carried on.

        No SPOF FTW!

      Re: Where's the redundancy?

      And there's me that has always kept a Three data SIM in an old Android handset as a backup to my Voda daily SIM. Now that Three and Voda are merging they're making a single point of failure out of 2 networks.

    My broadband ISP Onestream also fell over as they also use Vodafone for their infrastructure. DHCP was still providing my router with an IP address which would change after a few reboots but traceroute wouldn't get any further that the gateway, and pings to anything out on the internet would result in 100% packet loss.

    It back online now, DNS was a bit flakey at first but seems okay now.

    SMS wasn’t working for me. Voice calls for some reason took around 15 seconds before it started ringing but they did work. Absolutely nothing else worked. Trace routes couldn’t see anything behind my home router, or outside of my mobile on 4g.

      Text messages didn't work for me until I switched off "RCS chats" in the messaging app settings (Android). Then they went OK as regular SMS. Had new phone for a month, always end up turning off that feature.

    What a s***show

    Fiber optic AND cellular went down. I just had time to stroll to the Vodafone store where the staff told everyone it would only take 1 hours and was due to the engineers "merging the 3 and Vodafone infrastructure". 5 minutes later the team turned the lights off, closed the doors and went home.

    By the time I set up my backup cellular it was back on.

    Still, is a 50% monthly discount for an all Vodafone package still worth it?

    1. MyffyW Silver badge

      Re: What a s***show

      The problem with all anyone package is straight away there's potential* for both failing. True, diverse sourcing doesn't automatically deliver resilience, but with some knowledge of the underlying businesses it makes it less likely.

      *I know, in an ideal world they would be entirely separate, but I think this proves they often aren't.

          "This was triggered by a non-malicious software issue with one of our vendor partners which has now been resolved, and the network has fully recovered. We apologise for any inconvenience this caused our customers."

          basically they had one of their outsourced teams do some work on the system responsible for their BGP peering and something went badly wrong.

          why it took so long to roll back & why it happened during our day needs answering.

          as a VF customer years back we where implementing new WAN circuits and their converged voip solution, submitting requests for the voip stuff their offshore teams would ask me for details to complete their change request forms, instead of getting piecemeal requests I'd have them send me their form & I'd fill it out and send back to them, instead of 2 weeks of back & forth before they'd agree it I could get it done in 1 day. They were happy as they didn't have to do it & our customer was happy as their project got back on track.

          I realised then how vulnerable VF was to their offshore teams making mistakes.

          next job in a largish retailer, VF where the sole network provider, I did query why we didn't have 2 different providers given the risk of 1 provider having a major issue etc.

          they went down hard yesterday because of reliance on a single vendor.

          its not difficult to use multiple service providers in 2025.

    Tech is less resilient because it is complicated. A single component failure/unwise tweak can take anything down. This stuff will happen.

    …A reminder for us domestic users to address our own single points of failure. Keeping our cellular and broadband providers separate being one sensible move. As a Vodafone mobile customer I was getting a bit fed up with them spamming me with their broadband cross-sells. I’ll be even more fed up with these now. Vodafone management will be jumping up and down and looking for heads as the broadband initiative looked to be a key part of their strategy.

      We have Vodfone broadband and an IP phoneline via the router. We had no internet traffic during the downtime but we could call the "landline" phone's number from a mobile and get it to ring so something resilient was still working in the Magic Boxes back at the exchange.

      Yeah, surely at some point all their broadband and mobile network data ends up the at same data centres and/or trunks. It makes no real difference if the endpoint is a router in a customers home or network mast. At least from a business cost point of view.
