Incident History

The incident has been resolved and SMS delivery from a subset of Twilio Short Codes to Liberty Mobile network subscribers in Puerto Rico is operating normally.

The issue affecting voice calls from network subscribers to Twilio Spain Phone Numbers has been resolved, and the service is functioning normally at this time.

Twilio Voice ConversationRelay was degraded for 1 day 18 hours and 54 minutes between 18:29 Pacific Time on 03/24/2026 and 13:23 Pacific Time on 03/26/2026. During this period, ConversationRelay sessions could intermittently fail to terminate when the WebSocket Application sent an end message while still streaming text-to-speech tokens. If all tokens completed before the end message, the session terminated normally. However, if the end message arrived mid-stream, the remaining tokens were discarded and the session entered a state where it could not complete. Affected calls remained silent until the caller hung up or a 60-second safety timeout fired. In both cases, the callback did not receive the end message's handoff data, preventing call transfers from completing. The issue has now been resolved.
