SMS Delivery Delays

10:59 AM PST We can confirm increased error rates and delivery latency for a subset of SNS and Pinpoint customers delivering SMS messages via US toll-free numbers and some long codes. We are working with our partners to resolve this issue, and will continue to provide updates until the issue is fully resolved.

11:00 AM PST We can confirm that long codes are not impacted, only US toll-free numbers are impacted. We continue to work with our partners to fully resolve this issue.

11:12 AM PST We are seeing early signs of recovery, and continue to work with our downstream partners to fully resolve the issue.

11:38 AM PST We can confirm that the delivery of SMS messages for US toll free numbers has recovered. However, we continue to see issues with delivery receipts being delayed and are working with our downstream partners to resolve the issue.

2:44 PM PST Between 5:14 AM and 11:38 AM PST, we experienced increased delivery latency while delivering SMS messages using US toll-free numbers. Also starting at 5:14 AM, SMS message delivery receipts were delayed, which created a backlog of undelivered delivery receipts. We are continuing to work with our downstream partners to clear this backlog. Receipts for new SMS deliveries will also be delayed until this backlog clears. The issues have been resolved and the service is operating normally.
