    Looks like a major issue with Cogent Communications, We are shutting down our BGP Sessions with Cogent Communications so traffic from BT will route via other routes.

There is no estimated time to repair. The master ticket is HD305149368" We shall leave the Cogent BGP Sessions down at both Sov and Volta until we get an all clear notification.
