No, It's free...
Ignore the Ad above, just click "Begin Test", (not "Free Scan") It will find out how fast you upload and download. Then check try the ping test. I get a B plus connection here. 20 Mb/s Down, 3 Mb/s Up, 24 Mb/s Ping. I consider this pretty fast, considering my first modem was 14,500 K. Still, I get interupted streaming on video clips, my assumption is that the problem is upstream, somewhere.
I've never had a problem with this site.
