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.
Judgement day postponed indefinitely due to "Object reference not set to an instance of an object"
I don't know why but this is the first time I read this phrase and it actually makes sense.
I knew exactly what it meant before, but it didn't make sense until now
