## Updates from Cartesia

### resolved, 2026-08-14 09:34 UTC

This incident has been resolved.

### monitoring, 2026-08-14 09:31 UTC

We have mitigated the issue on our end and are continuing to monitor the state of our service.

### identified, 2026-08-14 08:07 UTC

The change has been rollbacked in APAC.

### identified, 2026-08-14 07:58 UTC

A change rejects unknown TTS language regions, e.g. `hi-in` is rejected since an ISO 3166-1 alpha-2 country code is expected. We are working on rolling back this change. To correct the issue immediately, avoid sending the country code or send a corrected country code such as `hi-IN`.
