Outage in Telnyx

Elevated API errors and missing cost data

Resolved Minor
August 05, 2026 - Started 4 days ago - Lasted about 19 hours

Incident Report

Summary AI Generated

Telnyx experienced an 18.6-hour incident where a degraded internal dependency caused elevated 503/504 error rates on Messaging API requests and missing or incomplete cost data on inbound message webhooks, Programmable Voice, and TeXML call records. Message delivery itself was not affected throughout the incident. Error rates normalized and message retrieval returned to expected operation by resolution, though some records created during the incident faced a temporary processing backlog and may have retained incomplete cost data.

We are experiencing elevated error rates affecting a small percentage of Messaging API requests. Affected requests may return a 503 or 504 error and can be safely retried. Separately, cost data may be missing or incomplete on some records. This affects the cost field on inbound message webhooks, and call cost for Programmable Voice and TeXML. Message delivery is not affected. We have identified the cause as a degraded internal dependency and are working on a resolution. We will provide an update within 30 minutes.

All services are operating normally. Some message records created earlier during this incident may still take longer than usual to appear while a processing backlog clears. We are monitoring to confirm.

Error rates have returned to normal and message retrieval is operating as expected. Some recently created message records may still take longer than usual to appear while a processing backlog clears. We are monitoring to confirm the fix holds.

Inbound Messaging APIs have returned to normal operation.

The remaining impact is on retrieving message records. A percentage of GET /v2/messages/{id} requests may return a 503 or 504 error and can be safely retried. Sending messages, message delivery, and delivery webhooks are unaffected.

Cost data may be missing on some records created earlier during this incident.

Work on a resolution is ongoing.
