Yes I have two customers over there – one in VA and the other WV. I did not do traceroutes but I was observing strange activity. Both the PE and the CPE would respond to ICMP but VPN tunnel to corporate office down and my monitoring was down. I did notice the outages on downdetector over several states so I figured I would give it some time to resolve itself. My two offices just returned about 10 minutes ago. Thanks for the info about the routing loop. The Comcast rep I spoke with seemed oblivious to the situation. We’ll see what happens.

Interestingly enough, Downdetector is showing a large spike in down reports across a wide range of services all at the same time.
