## Updates from Vapi
### 2026-10-10 04:00 UTC: update
What is affected: Outbound calling
When: Tonight, Friday, October 9, 21:00–21:15 PT (04:00–04:15 UTC, October 10).
What to expect: Non-Campaign Outbound calls may briefly stall or fail to connect during the patch over a 5-10 minute period. We will validate the remainder of the window to confirm calls connect normally, and update this page when connectivity returns and maintenance is complete.
Action needed: None.

### 2026-10-10 04:15 UTC: update
Upgrade was successful. The API was unavailable for approximately one minute and is successfully sending outbound calls. Will continue to monitor health for the next 2 hours.
