The back and forth between Internet service providers (ISPs) and Netflix
as to which side is to blame for poor streaming performance continues with Verizon
penning a blog post saying its hands are clean. According to Verizon, it's not throttling streaming video from Netflix, and the reason why some of its customers with fast connections are experiencing poor quality video is entirely Netflix's fault, the ISP says.
Verizon claims to have investigated the issue after receiving a letter from a customer on a 75Mbps FiOS connection who wasn't receiving a good feed from Netflix.
"This review confirmed again what I’ve explained before: there was no congestion anywhere within the Verizon network. There was, however, congestion at the interconnection link to the edge of our network (the border router) used by the transit providers chosen by Netflix to deliver video traffic to Verizon’s network," Verizon said.
In short, Verizon says the links chosen by Netflix get congested, while links from other transit providers carrying non-Netflix traffic do not and therefore perform fine.
"Netflix chose to attempt to deliver that traffic to Verizon through a few third-party transit providers with limited capacity over connections specifically to be used only for balanced traffic flows. Netflix knew better. Netflix is responsible for either using connections that can carry the volume of traffic it is sending, or working out arrangements with its suppliers so they can handle the volumes," Verizon added.
Though Verizon is claiming the situation is entirely Neflix's own fault, the ISP says it's working "aggressively" with the streaming video provider to establish new, direct connections that will alleviate the issue without prioritizing Netflix traffic in any way (thereby sidestepping net neutrality concerns).
