Authentication failing intermittently

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

Authentication is failing intermittently across services — tokens 'expire' immediately or signatures fail to validate — and nothing was deployed. What's a likely cause and response?

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.
