Event Summary
One of our underlying carriers, Brightlink, was affected by an outage with one of their upstream providers. This outage caused inbound calls to numbers housed with Brightlink to play a message stating that this was a test number. This outage only intermittently affected callers on AT&T, Verizon, and T-Mobile. Brightlink was already aware of the issue and resolved it by making a route change to inbound calls. We will continue to monitor them closely and report as we have updates. We apologize for any disruptions.
