Got into work to a dead SQL server. Rebooted last night, someone (not us) made some undocumented changes to the OS and the DB server settings and it had switched query plans for one of the main sprocs to something dumb.
Pinned an old plan, no joy. Took down everything but the web app. No joy. Only by being a curious dev-DBA did I work out what had changed. Two hours to get it back on its feet. Utterly exhausted my team and me. Bleh. Bad start to the week.
