Re: resilience
That's fine if you can arrange the resilience. Plain old telephone lines are (were) self powered by batteries at the exchange, precisely so that emergency calls would be possible when mains electricity failed. Now that's all being stripped out for fibre and VoIP, so it's your job as a confused pensioner to specify and fit a suitably rated UPS. Public organisations (by which I mean government, banks, utilities etc) used to have multiple ways of contacting or paying. Now, the woodworm economists are eating all that away on cost grounds. So since the local office is long gone, you call a phone line and get a recorded message telling you to go to the website and send an email. An address to write to? Not likely. The bottom line is that we are all being herded into using the internet with little or no attention to those left behind and what may happen when the system fails.
I'm not against progress - looking at the situation in Ukraine, internet and mobile communications are all that is still working in some places. But the whole point of resilience is to avoid single points of failure, not move to new ones.
