We have added June data to the Netflix ISP Speed Index, our monthly update on which Internet Service Providers (ISPs) provide the best prime time Netflix streaming experience.
With this month’s update, we also have included icons in the U.S. graph to increase transparency about the type of technology used by an ISP. This should make it easier to compare Netflix performance on different types of networks.
Here are some data points from this month's update:
- US: Among the major ISPs, Cablevision, Cox and Suddenlink continue to lead the index and show steady improvements over the last three months. Meanwhile Verizon FiOS continued its decline, dropping another two spots to No. 12. Both Verizon FiOS and AT&T U-Verse rank behind DSL offerings from Frontier, Windstream and Centurylink.
- Canada: After breaking out DSL and fiber from MTS and Sasktel, fiber networks of both providers ranked high in performance, with MTS Fiber taking the third spot and Sasktel Fiber coming in fifth.
- Latin America: Telecentro retained the top spot in Argentina, increasing its performance by almost 1 full Mbps, rising to 3.26 Mbps from 2.35 Mbps.
- Europe: While there was no significant change at the top of the rankings, Virgin Media in the UK did expand its lead over BT as the No. 1 ranked provider.
The Netflix ISP Speed Index is based on data from the more than 48 million Netflix members worldwide who view over 1 billion hours of TV shows and movies streaming from Netflix each month. The listed speeds reflect the average performance during primetime 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 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.
The latest regional rankings are below.
