I'm using Remote Desktop to access my PC at a friend's house across the county and my connection keeps getting interrupted. He's on Comcast and his head-end is in Pinole. My Sonic head-end appears to be in El Sobrante. Using Matt's Traceroute (mtr) on Linux at both ends, I can see the packets going from Pinole on Comcast to Santa Clara, then on Sonic to Colma, San Rafael, Richmond, and El Sobrante. What a grand tour of SF Bay! It might be a good idea to run a trunk from Comcast's Richmond data center to Sonic's El Sobrante location. The area's growing so that might cut your peering costs.
I also see 80%+ packet loss in the 2 Sonic routers on either side of the San Rafael bridge.
I also learned not to trust the reverse DNS names. His first two hops are to routers claiming to be in Pleasanton, and he knows the drop goes to Pinole. But Comcast is always renumbering their network, so I suspect they moved a chunk of their addresses from Pleasanton to Pinole and didn't update their reverse DNS to match.
If Sonic runs fiber through Alhambra Valley (between Pinole and Martinez), he'll switch in a heartbeat. (But retain Comcast as a backup.)
Edit: The intermittent disconnection is Comcast, not Sonic. I've got Comcast as my backup and I changed my route to go through that, which is a short hop, and I'm still dropping Remote Desktop.
