## 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.

This incident has been resolved.

From the builder: does your app depend on Plivo? [Sazabi](https://www.sazabi.com/?utm_source=down-guide&utm_medium=markdown&utm_content=plivo) detects problems in your own logs without hand-written monitors, and you can ask it in plain language which errors mention Plivo.
