The reason VPN works is that Comcast was deliberately degrading Netflix's data stream and VPN conceals the nature of the traffic.
If this was the case other services operating on Cogent wouldn't be degraded, but they are. For example, League of Legends was a casualty of this problem and it forced them to make changes in their hosting arrangements.
Don't confuse any of this with "Net Neutrality" - there is no evidence of subscriber connection degradation by The Man, no matter how many hipster technocrats publish urgent tweets to the contrary..

A-C connection is saturated is an issue for A or C, Not the client or the server.
A never went to bill the server, A went to C, because C was generating all the traffic, and C said fuck you, so server went to A and said here's the cash that C won't give you. C made it a server problem, in this case. Peerage is based on an even trade.. the problem is the trade isn't even
