Unreproducible intermittent failure

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

You're chasing an intermittent failure that you can't reliably reproduce — it happens occasionally in prod but never on demand. How do you approach 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.
