Intermittent Calling Impairment
Incident
Report for Bandwidth
Resolved
Bandwidth has been advised by AT&T that their network has restored and calls are processing as expected. The Bandwidth NOC Team has also verified we are seeing calls process as expected via AT&T for both Voice and 9-1-1 Traffic. We consider this incident resolved and are closing this incident.
Identified
Bandwidth is seeing improvements within the AT&T Network, however, some intermittent impairments are still being observed by our NOC Team- but at a much less frequent rate. This applies to both Voice and 9-1-1 Traffic. The Bandwidth network has remained stable and processed calls as expected during the duration of AT&T's impairment.
Update
At this time, specific markets in the southeastern US could be impacted for inbound and outbound services. Bandwidth NOC continues to escalate this issue with AT&T to determine the cause and resolution. The markets impacted are 420 - Asheville, 422 - Charlotte, 424, Greensboro, 426 - Raleigh, 428 - Wilmington, 430 - Greenville, SC, 432 - Florence, SC, 434 - Columbia, SC, 436 - Charleston, SC, 452 - Jacksonville, FL, 454 - Gainesville, FL, 458 - Orlando, FL, and 460- Miami, FL.
Update
At this time, only AT&T SouthEast (legacy BellSouth) regions are impacted for inbound and outbound services. 9-1-1 calls are processing as designed during an industry impairment of this kind. As AT&T is having interment impairments with selective routers, Bandwidth Customers may notice some 9-1-1 calls processed by our Emergency Call Center and ultimately by the proper PSAP.
Investigating
Bandwidth is observing an impairment within AT&T's network intermittently affecting industry calls including calling to the Bandwidth Network. We are actively engaged with this carrier and will provide updates as available.
