Where is Internet Congestion Occurring?

In my post last week, I explained how Netflix traffic was experiencing congestion along end-to-end paths to broadband Internet subscribers, and how the resulting congestion was slowing down traffic to many Internet destinations. Although Netflix and Comcast ultimately mitigated this particular congestion episode by connecting directly to one another in a contractual arrangement known as paid peering, several mysteries about the congestion in this episode and other congestion episodes that persist. In the congestion episodes between Netflix and Comcast in 2014, perhaps the biggest question concerns where the congestion was actually taking place. There are several theories about where congestion was occurring; one or more of them are likely the case. I’ll dissect these cases in a bit more detail, and then talk more generally about some of the difficulties with locating congestion in today’s Internet, and why there’s still work for us to do to shed more light on these mysteries.

Is There a Future for Net Neutrality after Verizon v. FCC?

In a decision that was widely predicted by those who have been following the case, the Court of Appeals for the D.C.

The rules were challenged by Verizon as soon as they were enacted in 2010. The court held that, given the FCC’s past (and never reversed or modified) regulatory choice to classify broadband providers under the Telecommunications Act of 1996 as “information services” rather than “telecommunications services,” it cannot now impose on them common carrier obligations that apply under the statute only to services classified as telecommunications. Verizon argued in the case that the Open Internet Rules were not common carrier regulations, but the court didn’t buy it.
