I think it is worse than that. When I make a change to some code or config, I'll run it locally to make sure that the change has the effect that I want. I know that we are human and that bugs occasionally appear in code. But what I can't understand is that the human who initiated this change decided not to see if it actually did what they wanted it to do.

I've made changes on personal projects that I thought were simple, and yet broke stuff. But CrowdStrike is a multi-billion dollar company -- how can it be possible to have such a broken process. Their RCA document was interesting, but didn't cover any of the interesting issues. It seems that they don't know about the 5 Whys process (https://en.wikipedia.org/wiki/Five_whys) or decided that those answers were so embarrassing that they had to omit them.
