Earlier quoted context omitted.
.....no? "We deployed this private cloud with a missing parameter and it wasn't caught" is as different from "we wiped out all customer data" as hello world is from Kubernetes. No one promised this "should be impossible". Did you confuse "we'll take steps to ensure this never happens again"?
It's pretty much half the puzzle actually. You contend there's no global rm rf for a global cloud provider, but clearly a missing parameter can rm rf a customer in an irrecoverable manner. The only half you're missing is... how every major cloud outage happens today... a bad configuration update. These companies have hundreds of thousands of servers, but they also use orchestration tools to distribute sets of changes…
It's the sort of thing that used to keep me up at night.
