Twilio: SMS Delivery Failures from AT&T Network in the US to a Subset of Twilio's Numbers
Timeline of updates
- resolved
We continue to investigate the issue causing SMS delivery failures when sending messages from the AT&T Network in the US to a subset of Twilio's numbers. Because we expect this issue may take some time to resolve, we have opted to reach out to impacted customers directly about this issue while we investigate and we'll continue to provide updates through that channel instead of our status page. We will mark this incident resolved on the status page but will send any further updates through the direct communications channel.
From Twilio’s published incident history: for incidents before Rewindex began polling this status page, only the final update text is available.
Archive proof
Rewindex commits each version of an incident it captures to a daily checkpoint, chains it to the day before, and has the checkpoint timestamped by FreeTSA and DigiCert.
How the archive is checked, and what it cannot prove.
This incident predates live tracking (October 17, 2026). It came from the vendor’s own published history, which is not covered by checkpoints.
Impact, status and times are the vendor’s own, as last archived. View on status.twilio.com (opens in new tab).
