Below is November data for the Netflix ISP Speed Index, our monthly update on which Internet Service Providers (ISPs) provide the best prime-time Netflix streaming experience.

A look at year-over-year average performance since November 2013 shows significant increases in average speed in the U.S. and Europe.

In the U.S., the average speed for the top 10 cable and fiber ISPs increased over 1.00 Megabit per second (Mbps)  in the last year, rising from 2.03 Mbps last November to 3.07 Mbps today — in part because numerous ISPs including Cablevision, Cox and Charter increased their average speeds significantly without requiring additional payment to reach mutual customers.*  Additional interconnect capacity also helped normalize performance across these ISPs. Last November, the spread between the highest and lowest speeds among the top 10 was about 1.00 Mbps; today, it’s narrowed considerably to 0.33 Mbps.

We saw similar improvements in performance in Europe, including the UK and Ireland, with the average speed for the countries we’ve tracked over the last year increasing to 3.31 Mbps today from 2.62 Mbps last November. Ireland posted the biggest gains with its average speed jumping 1.00 Mbps to 2.78 Mbps. While all the European countries we tracked last November — except for the Netherlands, which was higher — averaged speeds below 2.85 Mbps, everyone except for Ireland topped 3.00 Mbps last month, including the six new countries added in September.
The Netflix ISP Speed Index is a measure of prime time Netflix performance on a particular ISP and not a measure of overall performance for other services/data that may travel across the specific ISP network. Faster Netflix performance generally means better picture quality, quicker start times and fewer interruptions.

*Certain ISPs — Comcast, Verizon, Time Warner Cable and AT&T — saw a significant increase in their average speeds only after Netflix met their demand for interconnection payments. We continue to believe the long-term health of the Internet is at risk if ISPs can demand access fees from content providers simply to reach consumers already paying for Internet service.
