So today I discovered that there's a cron job that holds non-reproducible state that died, and now our system is fucked.
The cron job doesn't live inside any source control. This morning it entered a terminal state, and because it overwrites its state there's no way to revert it.
I'm currently waiting for the database rollback and have rewritten it in a reproducible/idempotent way.
But the whole point of the doomsday machine is lost... if you keep it a secret! Why didn't you tell the world, eh?
It was going to be announced at his retirement party on Monday... You know the dev likes surprises.
