Partial outage affecting inbound AT&T Toll Free

Starting around 2PM CDT, we were alerted of unusual inbound Toll Free traffic patterns affecting numbers provisioned with AT&T. We immediately removed AT&T by activating our disaster recovery templates that exclude AT&T. The migration took approximately 30-45 minutes for all traffic to be off of AT&T. After removing AT&T from routing, we were informed that AT&T experienced a failure at the core of their network. Once AT&T verifies a fix has been implemented, we will confirm via in-house tests and metrics before adding AT&T back to our Toll Free templates.
