## Incident: Deepgram Service Outage

**Status:** Investigating
**Severity:** SEV1
**Started:** [TIME]
**Impact:** All transcription services unavailable

### Summary
We are experiencing a complete outage of our transcription service due to
Deepgram API unavailability.

### Current Actions
- [ ] Verified Deepgram status page shows incident
- [ ] Contacted Deepgram support
- [ ] Activated fallback queueing
- [ ] Notified affected customers

### Next Update
In 15 minutes or when status changes.
