Everyone is posting jokes about GitLab recent incident and how the guys responsible for that must be feeling right now.
Shit happens, sometimes it's you accidentally deleting a branch on your repo and turning that into a major crisis, sometimes is a huge mistake that impacts not only the whole company business, but also it's clients work.

This situation reminds me of a famous quote from Thomas J. Watson (ex lBM CEO):

"Recently, I was asked if I was going to fire an employee who made a mistake that cost the company $600,000. No, I replied, I just spent $600,000 training him. Why would I want somebody to hire his experience"

Those guys at GitLab have probably learned one of the most expensive lessons in IT world and I really wish them to come up with a solution that not only fixes this case, but that helps them preventing future occurrences.
