Outbound SMS delivery delays

Affecting: SMS/MMS Gateway

Degraded Performance
identified 4d ago

Outbound SMS messages may show as Sent but not reach the recipient. This affects messages sent from both Switchboard (Flare SMS) and the Pulse app. Incoming messages are not affected and continue to be delivered normally. We have traced this to an active incident at our upstream messaging carrier, which began at approximately 2:00 PM ET on September 10. The carrier has identified the cause and is working to restore delivery. No action is needed on your part — affected messages may need to be re-sent once service is restored. We will post updates here as we receive them.

Resolved — September 11, 3:30 PM ET. Outbound SMS delivery has been restored and verified end to end. This followed an upstream messaging incident affecting delivery to certain destinations. Outbound delivery has been confirmed working again. If you sent a message between approximately 2:00 PM ET on September 10 and 3:15 PM ET on September 11 and it did not arrive, please re-send it. Incoming messages were unaffected throughout. Note: a message's delivery tick may take a moment to update in Switchboard and Pulse, and reloading the conversation will show the current status.
