## Timeline of updates

- **resolved** 2026-06-17 19:00 UTC: On June 17, 2026, between 11:35 UTC and 19:20 UTC, the Webhooks service was degraded and delivered webhook payloads with missing installation information. On average, 11.3% of webhook deliveries were impacted. Customers relying on the installation field for authentication or routing were unable to process affected webhooks. A smaller subset of deliveries for the security\_advisory event (0.04%) were delivered successfully but were not recorded for redelivery. This was due to a defect in a new delivery code path that failed to include installation data in webhook payloads. We mitigated the incident by disabling the feature flag controlling the new code path. We are working to improve our automated validation of webhook payloads, and introduce automated alerting for webhook payload regressions to reduce our time to detection and mitigation of issues like this one in the future. The following events were affected: branch\_protection\_configuration, code\_scanning\_alert, commit\_comment, custom\_property, custom\_property\_values, dependabot\_alert, deploy\_key, deployment\_protection\_rule, deployment\_review, dismissal\_request\_code\_scanning, dismissal\_request\_secret\_scanning, installation\_target, member, membership, merge\_queue\_entry, org\_block, organization, projects\_v2, projects\_v2\_item, pull\_request\_review\_thread, repository\_ruleset, secret\_scanning\_alert, secret\_scanning\_alert\_location, secret\_scanning\_scan, security\_and\_analysis, star, sub\_issues, team, team\_add, workflow\_job.
