Oh yeah, the big fiat banks' computer systems never fail – we can always rely on them...

NOT!!

A few weeks ago I drove my mum to the shop, put her bank card in the hole-in-the-wall (she can do this herself, but her eyesight isn't great so I sometimes do it for her). Her card disappeared into the machine, never to be seen again! I hadn't received any errors about the PIN number being entered incorrectly, or anything like that...
Mum phoned the bank, and they blithely apologised and told her that "the machine had decided to reset itself just at the moment that her card was being entered". That was that. She had to wait to get a new card and PIN number posted out.
On several occasions people have found that their cards just don't work in card machines or at tills, because of "a major fault that affected the LINK network yesterday afternoon and evening". This kind of thing happens whether you're using fiat or crypto.
Re-checking your voting power. I use steemd.com/[@username]. It sometimes goes down too, which is always frustrating - but there are other tools too.
And by the way you did mention aliens in your post on the Pyramids. But that's not a criticism! It's always good to read your posts.
