Internet service provider (ISP) performance is notoriously hard to quantify, but there's at least one company that has tons of real-world data: Netflix.

The streaming-video king released a report this morning ranking 21 major U.S. ISPs based on real-world streaming performance. Google Fiber came in the lead by quite at bit, with an average of 2.55 Mbps in November, with the next closest competitor (Verizon FiOS) coming in at 2.19 Mbps. Unsurprisingly, DSL services came in behind all the major cable/fiber services, with the best performer averaging just 1.42 Mbps in November. The best mobile service to crack the list is Verizon at a relatively pokey 0.76 Mbps.

Netflix says this is just the first installment in what will be a regular monthly report, which is good news for keeping ISPs honest about bandwidth throttling.
