Netflix has added the data for September to its ISP Speed Index, which looks at the ISPs providing their customers with the best Netflix streaming experiences.

As usual, Google Fiber leads the pack. In fact, there aren’t many changes for the month, except Bright House moved up a notch, and Mediacom moved down.

If you look at these lists regularly, you’ll notice it looks a little different this time. They’ve added the gradient bars to better illustrate the difference in performance from provider to provider.

The index is based on data from over 37 million Netflix subscribers and over a billion hours of streaming activity per month.

Last month, Netflix made its high quality HD streams available to all subscribers, regardless of ISP. The company says it doesn’t expect this to have much of an impact on the rankings.

Also last month, Netflix put out its first regional ISP speed index snapshot looking at the greater Boston area.

In related news, Netflix is reportedly in talks with a handful of U.S. cable providers to potentially get the Netflix app on some set-top boxes, as with recent deals with Virgin Media and Com Hem.
