An anonymous reader writes John Oliver calls it "cable company f*ckery" and we've all suspected it happens. Now on Steven Levy's new Backchannel publication on Medium, Susan Crawford delivers decisive proof, expertly dissecting the Comcast-Netflix network congestion controversy. Her source material is a detailed traffic measurement report (.pdf) released this week by Google-backed M-Lab — the first of its kind — showing severe degradation of service at interconnection points between Comcast, Verizon and other monopoly "eyeball networks" and "transit networks" such as Cogent, which was contracted by Netflix to deliver its bits. The report shows that interconnection points give monopoly ISPs all the leverage they need to discriminate against companies like Netflix, which compete with them in video services, simply by refusing to relieve network congestion caused by external traffic requested by their very own ISP customers. And the effects victimize not only companies targeted but ALL incoming traffic from the affected transit network. The report proves the problem is not technical, but rather a result of business decisions. This is not technically a Net neutrality problem, but it creates the very same headaches for consumers, and unfair business advantages for ISPs. In an accompanying article, Crawford makes a compelling case for FCC intervention.
