What is Fast.com?
Fast.com is a speed test run by Netflix. Open the page and it starts straight away, downloading test data from Netflix servers and showing the maximum speed your connection can reach. There is nothing to press and no account to make.
The first number is download speed, since that is what matters most for streaming. A "Show more info" link adds upload speed and latency, including latency under load, and a settings panel changes how the test runs. Netflix says it offers the test so members can get a simple answer on what their connection can do.
