Well, packet loss here really is a bandwidth problem, though. The packet loss happens because some link is saturated and packets are arriving faster than they can be transmitted, and TCP simply reacts by adjusting the sending rate so as to not exceed the available bandwidth at the bottleneck. Still true that the problem often is more the peering than internal infrastructure, yeah.
