Upstash change history: QStash US Region Service Disruption

QStash's US-EAST-1 service suffered a critical disruption starting 2026-05-08 09:46 UTC, lasting 22 min and resolving at 2026-05-08 10:08 UTC. Upstash implemented a fix; its partial postmortem links the incident to a scheduler bug introduced in US East (N. Virginia), triggered when a user with active schedules deleted their account.
