Suppose there is more to the story and your bank is unable to recover the account balances because for some reason they put the bitlocker key into the cloud which is also bitlockered in a boot loop. Yes, don't laugh, someone I know has done this. I would have thought a bank would have safety deposit box facilities, but hey, who knows.
Suppose there is more to the story other than a harmless update and somehow your account balance is zeroed.
What are you going to do?
How resilient is our infrastructure? Why is it always an Australian that blows up something, be it Optus or Crowdstrike?
You would think that the banks would have priority access to IT professionals, but maybe Australia is just a banana republic in disguise? A tweet stating, a simple "Our IT professionals are doing a recovery from last night", all is good, but nothing from the big 4. That is really surprising there is no update which means maybe something bigger is the underlying issue.
How long do you think it will take to recover?
it's not an Australian company. if it's affecting you, claim your losses from your bank.
