Notice July 24, 2026 Incident With Blocked GitHub.com Traffic –
Started Jul 24, 2026, 11:00 AM UTC· resolved Jul 24, 2026, 11:00 AM UTC
- resolved Jul 24, 2026, 03:56 PM UTC
Between July 23, 2026 at 18:45 UTC and July 24, 2026 at 11:19 UTC, an abuse mitigation update caused some legitimate customers whose traffic was routed through our Central Europe and South America edge locations to be incorrectly blocked from GitHub.com. We estimate that approximately 0.25% of GitHub.com requests were affected during this period. This was caused by an abuse mitigation configuration that incorrectly classified legitimate traffic. We mitigated the incident by reverting the update. We are adding validation and safeguards to prevent similar incorrect blocking in the future.

Notice June 17, 2026 Incident With Webhooks –
Started Jun 17, 2026, 07:00 PM UTC· resolved Jun 17, 2026, 07:00 PM UTC
- resolved Jun 19, 2026, 02:38 PM 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.
