## Updates from Plivo
### 2026-08-25 07:25 UTC: identified
Dear Valued Customers,
We are currently observing an intermittent issue where a subset of voice calls are not triggering status callbacks, including ringing, hangup, and call-status webhook events. Call processing itself is unaffected, and calls are connecting and completing normally.
We have identified the cause as a degraded event-processing component on a subset of our media servers and are actively working on remediation. The impact is intermittent, and most calls continue to receive webhooks normally.

### 2026-08-25 07:41 UTC: monitoring
A fix has been implemented and we are monitoring the results.

### 2026-08-25 14:16 UTC: resolved
This incident has been resolved.
