Netflix has released figures for January ranking Internet Service Providers delivering the best viewing experience for viewing Netflix’s catalog of online video titles.

At the top is Google Fiber, which comes as little surprise considering Google provides 1,000/1,000Mbps service to its limited number of customers in Kansas City.

Suddenlink saw the greatest improvement. The mostly-rural and small city cable provider jumped five points in January’s ratings, scoring 3rd. Cablevision’s Optimum broadband service jumped ahead of three rivals to score second place.

Time Warner Cable and Cox remained in the middle, while AT&T U-verse demonstrated that the benefits of a fiber network end when the remaining copper wire to the customer’s home comes into play. U-verse performed only marginally better than the DSL services of independent phone companies like Windstream and CenturyLink. Frontier managed some minor improvement, now scoring 14th place out of 17.

The worst performers: DSL services from both Verizon and AT&T and Clearwire’s 4G WiMAX network, which scored dead last.
