The truth about Netflix’s Fast.com

Netflix recently introduced Fast.com — yet another broadband test that purportedly allows you to measure the speed of your Internet connection. While this might seem like a good way for customers to hold their Internet service providers (ISPs) accountable, the speed test actually says very little about ISP performance: Despite the claims of tools such as Fast.com, ISPs do not control end-to-end packet delivery speed. The tool will not tell customers the speed Netflix actually uses. But if the speed test doesn’t provide an accurate picture of your broadband connection, why did Netflix create it?
