It's only tangentially related to region. Comcast bring all of Netflix's traffic onboard in NYC and their East Coast routing is handled in New Jersey. Their eastern seaboard routing is about the only area where they're not having massive internal issues. Both their Denver (Midwest) and Oregon (PNW) iBone routing centers are having serious capacity issues that are manifesting as packetloss, giant latency increases and generally shitty route-arounds in the hope that it'll relieve pressure.

- aroch 13y agoWhy does Comcast use so few peering locations? Because its cheaper to build and maintain only a few hubs. It's also cheaper for them to only onboard traffic a specific centers. JFK is the big US routing hub for Cogent and has the benefit(?) for Comcast of being where all the other big US ISPs onboard Cogent traffic. This lets them collectively bully Cogent (and other providers) into paying higher access fees. Why do they route packets from their network to a university in the same city across half a dozen states? I couldn't really say, likely its more related to what that university is paying for. I don't see any unis in Comcast's BGP announcement meaning they're probably going over Comcast's "Business" or "Corporate" network (higher priority traffic, same network). Comcast does not have very fine-grain regional routing, especially in the Midwest, so you'll see connections that cover a short LOS take a long path due to lack of routing
