investigating
We have stabilized Code Search infrastructure, and are in the final stages of validation before slowly reintroducing production traffic.
investigating
We are still working on recovering back to a serviceable state and expect to have a more substantial update within another two hours.
investigating
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.<br /><br />We will update again within 2 hours.
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.
