Disruption with GitHub's code search

Apr 1, 23:45 UTC Resolved - This incident has been resolved. Thank you for your patience and understanding as we addressed this issue. A detailed root cause analysis will be shared as soon as it is available.

Apr 1, 23:45 UTC Update - Code search has recovered and is serving production traffic.

Apr 1, 22:00 UTC Update - We have stabilized Code Search infrastructure, and are in the final stages of validation before slowly reintroducing production traffic.

Apr 1, 19:37 UTC Update - We are still working on recovering back to a serviceable state and expect to have a more substantial update within another two hours.

Apr 1, 17:48 UTC Update - We are observing some recovery for Code Search queries, but customers should be aware that the data being served may be stale, especially for changes that took place after 07:00 UTC today (1 April 2026). We are still working on recovering our ingestion pipeline, and synchronizing the indexed data.

We will update again within 2 hours.

Apr 1, 16:00 UTC Update - We identified an issue in our ingestion pipeline that degraded the freshness of Code Search results. While fixing the issue with the ingestion pipeline, a deployment caused a loss of dynamic configuration which is causing most requests for Code Search results to fail. We are working to restore the service and to re-ingest the misaligned data.

Apr 1, 15:02 UTC Investigating - We are investigating reports of impacted performance for some GitHub services.
