What to do

  • Check whether you use GitHub Webhooks, Issues, Pull Requests, Actions. Check your stack

    Paste a package.json, lockfile, Terraform or a list of domains at down.guide/stack to see every provider you depend on.
  • Confirm your retries, queues and scheduled jobs caught up after the 1h 45m it lasted.

    Anything that failed between 2026-07-23 07:53 UTC and 2026-07-23 09:39 UTC may need a replay.

  10. resolved

    On July 23, 2026, between 07:08 and 09:39 UTC, several services experienced delays: 8% of actions workflow runs experienced an average run start delay of 10 minutes, 5% of webhook deliveries exceeded SLO, and code scanning, repos, notifications, issues and pull requests experienced increased latency over the life of the incident. The root cause of the incident was a node of our background job processing system which did not recover after entering scheduled host maintenance. The incident was mitigated by identifying the problematic shard and restoring its correct state, after which queue backlogs drained and services recovered. To speed mitigation, we have added monitors for nodes in this unhealthy state after maintenance operations. To prevent future recurrence, we are adapting our lifecycle automation to verify host rejoin after a scheduled reboot.
