[outages] Comcast outages in Denver metro area

Anyone aware of any Comcast outages in the Denver area? Have a number of VoIP clients that are on Comcast circuits around the Denver metro area that are all down right now. I monitor their gateways in Nagios too and they are all 100% down at present. Trying to access them via Cogent and Level3 with the same results - 100% failure. Thanks. Chris
