Dang, your failure modes certainly are extreme. What companies actually performed a from-scratch rebuild because they failed to take a backup or thought "today's thursday, it's too complicated to restore!"?

There used to be a time in history when a system administrator had to know all this shit in order to keep their job. I guess nowadays devops just means dev as we furiously pump tokens into the AI Wurlitzer whenever we dont know how to do something and hope it doesnt gaslight us into deleting prod.
replyThanks, that sentence made my day.
