Problems with MT (Outgoing) SMS

Incident Report for GatewayAPI

Resolved

Message processing on GatewayAPI.com is back to normal, and all queued messages have been delivered. We’re keeping a close eye on the platform.

What happened
 From 16:02 CET (15:02 UTC) to about 18:15 CET, outbound messages from GatewayAPI.com were delayed. Our API was up the whole time and accepted every message sent to it. Some messages waited in our queue longer than usual before going out to the networks.

Impact
Only GatewayAPI.com customers were affected. Other GatewayAPI platforms were not.
No messages were lost. Every accepted message was queued and delivered, some with a delay.
No data was exposed or breached. This was a performance problem, not a security incident.

What we’ve done
We traced the problem to how our internal message-processing workers pick up messages from the queue. We changed that setting, and normal processing resumed right away. As a precaution, we’re running with extra processing capacity and have added more monitoring while we confirm the root cause.

Next steps
We’re still looking into the underlying cause, including a suspected problem in one of the software components our processing workers depend on. We’ll publish a full post-incident review here within 48 hours with the root cause and the steps we’re taking to stop this from happening again.

We’re sorry for the disruption and thank you for your patience. If you have questions about specific messages, please contact our support team.
