Reed Hastings: Comcast no longer following net neutrality principles
There is some ambiguity about where bandwidth accounting should take place: on the last mile link between the customer and Comcast or the transit link(s) between Comcast and the Internet. Comcast claims that anything coming from a server inside Comcast itself (e.g. Xfinity) should not count against the cap because it causes no congestion; this assumes that the cap exists only to prevent congestion on the transit side. I suspect that this is all just post facto justification, though.
