Error triage, failure post-mortems and automated repair.
Most teams have something watching production and something helping them write code. Both are good at their job, and neither one covers the hours between an error appearing in a log and a fix being on the server.

Read the articleOne sentence on a white page, and no clue which of four very different problems you have. The good news is that two minutes of checking separates them, and only one of the four is genuinely bad news.
Read the articleA 500 carries no information by design. The real error exists, it is just written somewhere you are not looking. Here is the order to check, per stack, and how to tell a 500 from a 502 before you waste an hour on the wrong layer.
