Rollback blocked by migration

On-callReliability & on-callSenior–Staff~20 min

An incident calls for rolling back a bad deploy, but the rollback is slow or impossible — a database migration already ran, or the old version is incompatible with the new data. How do you handle it?

What a strong answer looks like

Stop the bleeding first (mitigate), then form hypotheses from real signals. Separate root cause from symptom, communicate status as you go, and close with what prevents a repeat.

Which questions mattered is sealed until you submit. Telling you now would just be handing over the edge cases.
