Anyone seeing things like this when routing out from Comcast to Hostway? 
We're seeing total packet loss going out to 66.232.159.0/24 (i.e. 
www.powermedium.com) and others (8.6.221.0/24 also)

If someone at Comcast can check on this would be appreciated..

Routing seems to be dying at the level  3 handover
