I am not a rich person, although I'm comfortable, but several of my banks are terrible at IT. Like "We are upgrading our web site so it won't be available until Tuesday" level bad at IT.
Note that wasn't just "Some services won't be available", the whole web site was out of action for most of a day. It's disappointing but understandable if I can't send a random stranger 2500 ¥ at 2am because the bank are upgrading something. But it's straight up crazy that I can't even see my 2018 bank statement PDF because they're upgrading, it's the sort of feature a PHP Blog site can make work.
