As a person that has been watching this kind of horror stories from outside, I just wonder why people choose to make business with companies that have no human in the loop when stuff gets serious.
AFAIK, for AWS for example, when things get serious you are prompted to upgrade to a the big boi support plan (1.5k$/month) and are assigned a TAM (Technical Account Manager). In a situation like that, if you were running on AWS, a TAM or any human in general would have probably fixed the whole thing in like 30 minutes (if anything, because they would know you and that your usage is legitimate).
