This is why Netflix started their own (fast.com), making it more difficult for ISPs to throttle NF video content (or just prioritise speedtest traffic) and blame NF for poor performance (or poor quality because it was using more highly compressed streams to deal with low throughput) because “if you run any speedtest you'll see your connection through us is fine, it must be NF being busy”.
