I guess atleast the speedtest numbers are high.

I've been getting about 80 mb/s. Still outperforms the only available alternative in my area by 500x.

Interesting - must be regional I guess, I get good speeds where I use it.

I think you might wanna look at speedtest.net data

RE #2: fast.com has me at 1/3 of what speedtest.net has me for download.

No worries.. best of luck with that. As a total aside, fast.com is giving me 420mbps which should be impossible given my wifi setup. :/

Wasn't this what fast.com was created for?

Maybe your ISP is generally throttling your traffic but whitelisting speedtest et al to hide it.
