• Check whether your product depends on GitHub. 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 0m it lasted.

  Anything that failed between 2026-03-10 23:00 UTC and 2026-03-10 23:00 UTC may need a replay.

   On March 10, 2026, between 23:00 UTC and 23:40 UTC, the Webhooks service was degraded and ~6% of users experienced intermittent errors when accessing webhook delivery history, retrying webhook deliveries, and listing webhooks via the UI and API. Approximately 0.37% of requests resulted in errors, while at peak 0.5% of requests resulted in errors. This was due to unhealthy infrastructure. We mitigated the incident by redeploying affected services, after which service health returned to normal. We are working to improve detection of unhealthy infrastructure and strengthen service safeguards to reduce time to detect and mitigate similar issues in the future.
