That seems to be the status quo. I'm curious if the current trend is enough to break that tradition.
Or maybe breaking stuff is celebrated? For every type of downtime there will be lessons learned.
Every place I'v worked has celebrated fixing things that have broken, and forces engineers to fight for prevention. It's not exactly celebrating things breaking, but it sure looks a lot like it.
That's only true if lessons are learned. If an outage happens and you do nothing to fix it (or worse, do something entirely too specific without fixing the real problem and thinking you've done it) the exact same problem will happen again and you'll get another opportunity to not learn the lesson.
