Starting today, we’ll publish monthly rankings of major ISPs based upon their actual performance across all Netflix streams.
Google Fiber is now the most consistently fast ISP in America, according to actual user experience on Netflix streams in November.
Broadly, cable shows better than DSL. AT&T U-verse, which is a hybrid fiber-DSL service, shows quite poorly compared to Verizon Fios, which is pure fiber. Charter moved down two positions since October. Verizon mobile has 40% higher performance than AT&T mobile.
The average performance is well below the peak performance due to a variety of factors including home Wi-Fi, a variety of devices, and a variety of encodes. The relative ranking, however, should be an accurate indicator of relative bandwidth typically experienced across all users, homes, and applications.
