I acidentally destroyed the production system completely thru improper partition resize. We got the database snapshot, but it's in that server as well. After scrambling around for half a day, I managed to recover some of the older data dumps.
So I spun up the new server from scratch, restored the database with some slightly outdated dump, installed the code (which was thankfully managed thru git), and configured everything to run all in an hour or two.
The best part: everybody else knows this as some trivial misconfiguration. This happened in 2021.
