On June 17, 2026, between 16:57 UTC and 19:14 UTC, Copilot code completions were degraded and users were unable to receive Next Edit Suggestions. Standard ghost text code completions were not affected. This was due to a configuration change that caused the service's routing layer to incorrectly discard all Next Edit Suggestion model endpoints as invalid.<br /><br />We mitigated the incident by deploying a corrected configuration change at 18:55 UTC, with full recovery observed at 19:14 UTC.<br /><br />We are working to improve the resilience of our routing layer to limit impact due to a subset of invalid configurations, and to improve our alerting to detect sudden traffic changes that are not captured by standard error rate monitors.

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.

Between 17:38 UTC and 18:22 UTC on June 15, 2026, approximately 83% of requests to the analytics endpoint serving the /chronicle feature failed.  The cause was an internal feature-flag service that encountered a transient error and failed to recover, causing feature flag checks to fail. The analytics endpoint was gated behind one of these flags, resulting in requests being rejected. We restored service health by removing the feature flag gating the analytics endpoint and deploying that change. To avoid recurrence of similar incidents, we have changed the feature-flag client so that errors that are not known to be permanent are retried, and we are improving alerting and startup behavior so this class of failure is detected and recovered from faster.
