Incident History
April 2026
Disruption with some GitHub services
Started: Apr 2, 5:49 PM
investigating
Although we are observing recovery once again, we expect continued periods of degradation. <br /><br />Work that is queued during times of degradation does eventually get processed. <br /><br />We continue to investigate and find a mitigation, and will update again within 2 hours.
Apr 2, 8:35 PM

We are still working on recovering our ingestion pipeline, and synchronizing the indexed data.<br /><br />We will update again within 2 hours.
Apr 1, 5:48 PM
investigating
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.
