  4. Monitoring

    We identified the source of errors affecting Pull Requests, Issues, and Search on GitHub.com and have applied a mitigation. A database index hint was referencing an index that had been removed by a recent migration, causing query failures for some users. We disabled the problematic configuration and are seeing recovery across affected services. We are continuing to monitor to confirm full resolution.
