Potential Messaging Delays

The heightened awareness period is now over.

Twilio is reporting recoveries from delays, but we expect to continue to see delays intermittently throughout the holiday season.

Twilio is experiencing MMS Delivery Receipt Delays to US T-Mobile Network via Subset of Toll Free Numbers. You can find more information around the status of these delays at the provided link. Message sending is not affected.

We are now back to 100% capacity. We remain subject to carrier throughput limits during holiday time, however.

Twilio is experiencing another partial API outage. We have cranked down our throughput to less than 5% of usual to limit damage.

We are now back to 100% capacity and the queue has drained on our side. We remain subject to carrier throughput limits during holiday time, however.

We have now further increased throughput to 50% of normal, and continue to monitor closely. The current backlog on our side is around 75k messages. Twilio queues will also contain messages, not tracked by this number.

We have accrued a significant backlog of messages, after we cut our throughput from 100% to 9%. We are now cautiously ramping up throughout, raising from 9% of normal capacity to 22.5%. We will continue to ramp up, subject to communication with Twilio remaining reliable.

Twilio is reporting delays and intermittent failures in API usage as of 11:51AM. We have lowered throughput for some messaging services to offset potential delays in the Twilio Messaging API and will be monitoring the status updates from Twilio. You can find more information directly from Twilio on their incident page.

As of this morning, Twilio has transitioned all of yesterday's delay notices to now SMS and MMS carrier maintenance notifications for the US and Canada. We expect delay notices to reappear throughout the rest of the holiday weekend and early next week.
