provider
- postmortem
**What happened** An issue related to our speaker diarization service caused certain requests to hang until they timed out. This lead to a backlog of requests to our async API creating a processing queue across our US transcription pipeline, which slowed and timed out transcription requests more broadly, including requests that were not using speaker diarization. --- **When** Impact ran from approximately 15:00 to 16:25 UTC on June 25, 2026 \(about 1 hour 25 minutes\). The most severe disruption was in the first 45 minutes \(15:00–15:45 UTC\); remaining delays and timeouts cleared shortly after. Full recovery was confirmed by ≈16:40 UTC. --- **What services were affected** On our US async API endpoint transcription requests during this window saw processing delays and timeouts. Our EU async API endpoint was not affected and operated normally throughout.
