Vercel change history: Increase in Workflow runs stuck as pending

Vercel reported a major Workflow degradation: some recently deployed projects had runs stuck as pending and queued messages were not delivered. The incident lasted 5 h 58 min, from 2026-06-25 07:45 UTC to 2026-06-25 13:43 UTC. A fix was fully rolled out; the interim workaround was rollback to a working deployment created before Jun 24 21:00 UTC.
