This doesn't seem mysterious or confusing to me. What happened wasn't the launch of a new random power outage feature - it was a problem that needs to be fixed.

Fixing the bug does not necessarily fix anything else it caused though, and none of the questions in my post are answered by “fix it”.

Here’s another one: should the incident actually have an impact on anyone of the companies employees yearly reviews? Either positive or negative? Why?

It seems like you're conflating blame with bugs.

[mononcqc]

Well if all you have is bugs but you never look into how they get there and how they happen, you’re not going to improve your process or tools much.

Also blame and accountability and responsibility are all subtly different.
