I'm a huge fan of https://speed.cloudflare.com/ and you'll have to come with better evidence. Also fast.com doesn't even give upload speed and latency. - Source: Hacker News / 5 months ago
I had not heard of http://speed.cloudflare.com either. I just tried it and I did not get accurate numbers. wifiman.com, from Ubiquiti/Unifi team does provide more accurate numbers. fast.com numbers are pretty accurate as well. - Source: Hacker News / 5 months ago
I recommend the tests listed in https://www.bufferbloat.net/projects/bloat/wiki/Tests_for_Bufferbloat/: - https://www.waveform.com/tools/bufferbloat - https://speed.cloudflare.com/ - https://test.libreqos.com/. - Source: Hacker News / 5 months ago
