do you suspect that your isp is choking your bandwidth chicken, strangling your bitstreams, throttling your gmail and otherwise cheating you out of the bandwidth you paid for? you're not alone. the issue is, how prove it?
and then came google.
using several scattered servers, google now provides free access to online tools that can help you determine if your isp is taking a byte (lame, we know) out of your bandwidth. caveat emptor!
(come bask in the googley goodness with us. you know you want to.)
