> panicking is a normal thing to do

I do not think that if the bot detection model inside your big web proxy has a configuration error it should panic and kill the entire proxy and take 20% of the internet with it. This is a system that should fail gracefully and it didn't.

> The real issue

Are there single "real issues" with systems this large? There are issues being created constantly (say, unwraps where there shouldn't be, assumptions about the consumers of the database schema) that only become apparent when they line up.
