So then it’s like Ookla Speedtest?

  Some ISPs might prioritize traffic to Ookla (or its mirrors) which makes the ISP look better than they really are. With FAST.com you can see if your ISP throttles traffic to Netflix in any way, which is desirable for the ISP but undesirable for you.

    Cool. So fast.com can't have traffic prioritised to it's domain? Shouldn't it better be fast.netflix.com or something?

      Fast.com doesn't measure the speed to stuff behind fast.com, it measures the speed to Netflix CDN nodes.

      If they prioritised traffic to fast.com then real production Netflix video traffic would also be prioritised Fast.com is just a nice domain to put it on. It could be fast.netflix.com or anything, it just loads the code to kick off the test

      fast.com uses video data from ntflxvideo.net

        Great. That makes sense then. Thank you!
