Jokes on you, you can't do a run on a bank where you can't login or take any money out.
More seriously, I would definitely move my money somewhere else if I had an account there. Not because I would worry that it will disappear (government insurance & all that), but just because this looks like the kind of problem which will take a long time to fix, and which could strike back.
You definitely can do a run on a bank where you can't log in - you come to the office (or mail a registered letter) with written instructions to transfer all your money elsewhere and close the accounts, and legally they have a quite limited time to comply, I believe one or two business days at most, until various EU consumer protection laws for financial products kick in.
Furthermore, there's a lot of process for switching banks that can be done by the customer through the bank they're switching to. While your savings may be stuck in TSC for some days, you don't need to go to TSC at all if you'd choose to switch your wages and recurring bill payments to somewhere else, you just go to the new bank.
Exactly.. you have clearly under-tested code that is in debug mode printing out all sorts of detailed error messages and systems team that is overloaded with errors and problems to triage. Talk about a ripe target.
That is stuff of nightmares
Like what? You can't take cash out from ATMs or from bank offices, you can't login so you can't make a transfer, some people can't use debit cards... so yeah, run.
