> Said the other way around: fast.com is great to see actual throughput from Netflix as opposed to some fake throughout from a dedicated speed test site for the exact same reason.
Yup. This is pretty much the reason Netflix created fast.com. They wanted a speed test service that couldn’t be gamed by ISPs. Many ISPs will prioritise traffic to know speed test services (like Ookla’s speedtest.net), making their services appear faster than they’re under more normal usage.
By placing fast.com on Netflix IPs, ISPs either have to prioritise all Netflix traffic (which they’re very unlikely to do), or accept that fast.com is going to provide a more realistic measurement of their performance.
