New ISP Performance Data For December

We have just added December data to the “Netflix ISP Speed Index,” our monthly update on which Internet Service Providers (ISPs) provide the best Netflix streaming experience during primetime.

Noteworthy in December:
  • Performance was up in all countries, except the US and Mexico. The US is now essentially at par with Ireland and slightly above Mexico in the bottom of the country-by-country averages.
  • In the US, Cablevision, Cox and Suddenlink continued to show performance increases, while Bright House and Comcast tumbled five spots and other ISPs such as Verizon and Time Warner Cable also showed slower averages compared to last month.
  • ISPs in The Netherlands continued to offer the best Netflix connectivity.
  • Virgin Media in the UK extended its lead, while Everything Everywhere replaced Talk Talk in the last spot on the UK ranking. There was no change in Ireland, where Magnet continues to lead.
  • No major changes in the Nordic region. Norway, Denmark, Sweden and Finland continue to show strong Netflix performance.
  • Megacable in Mexico increased its lead over the other ISPs, but there was no ranking change.

The Netflix ISP Speed Index is based on data from the more than 40 million Netflix members who view over 1 billion hours of TV shows and movies streaming from Netflix each month. The listed speeds reflect the average performance of all Netflix streams on each ISP's network and are an indicator of the performance typically experienced across all users on an ISP network. A faster network generally means a better picture quality, quicker start times and fewer interruptions.

Note: the average performance is well below the peak performance due to many factors including the variety of encodes Netflix uses to deliver the TV shows and movies as well as the variety of devices members use and home network conditions. These factors cancel out when comparing across ISPs.

Below is our current ranking of regional ISPs.
