I'm seeing references to something Ericsson contributes to their network. It would very interesting to see what went wrong and in particular, what caused the change or deployment to be "un-revertable". My money is on a cascade of issues, some of which were latent and only triggered today. This is, by far, the worst cell outage I've seen in the UK. There is zero connectivity via O2 in e.g. London, data or otherwise.

  I liked the "limited number of customers" yes that's true, it affect 2-3 companies, it's just that a single one of those companies had 32M customers. Ouch.

  Something that simple, given that full service still hasn't been restored?

There was worse on 7/7/2005 in London due to the bombings. Nearly all the providers fell flat due to overload including land lines and mobile phones. Also public transport was hosed. I walked 11 miles home in the end. FM radio was about the only thing working. Thank you cheap nokia! I have an iPhone now which is devoid of an FM radio but carry a multiband VHF transceiver with me most of the time now as that can pick up FM and do comms on 2m (I have an amateur radio license as well).

    If you're in the UK: https://rsgb.org/main/get-started-in-amateur-radio/ https://rsgb.org/main/get-started-in-amateur-radio/ If you're in the US: http://www.arrl.org/what-is-ham-radio http://www.arrl.org/what-is-ham-radio Anywhere else, check your local society. It's quite easy to get into and not particularly expensive. Less than $100 including a cheap handheld radio as a starting point.
