One thing that Fast.com doesn't say is the top speed that Netflix's servers can deliver. I have 250 Mb fiber connection, and Fast.com tops out at about 150 Mbps for me. Speedtest.net consistently shows 250-280 Mbps. But it's unclear whether the lower rate is Netflix's servers limit, or my ISP throttling them.
