Netflix has launched a new tool to show what ISPs are best for streaming. Using data collected from its global userbase, Netflix is in a unique position to show which ISPs offer the best streaming speeds...and which offer the worst. The tool shows the data in many different formats, including the chart seen below:

The default tool page shows a quick overview of numerous different countries. The fastest, slowest, and average streaming speed are displayed. Users can then dive into individual country's results and graph how they change over a period of time. The data currently only goes back to November of last year, but the data will be updated each month.

If you want to check out the index for yourself, head on over to Netflix's ISP Speed Index. Currently Google Fiber is the fastest for the United States and has only gotten faster during the time Netflix has data for. Clearwire is the slowest at just under half the average speed.
