Test if your ISP is manipulating BitTorrent traffic

More and more ISP's are now implementing Traffic Shaping to ensure that they provide all their customers a fast Internet experience (their words not mine). Some IPS's are open about their policies where others keep it quiet. So how can you find out if you ISP it playing with your traffic?

I asked myself this very question and found this useful web application. It works by connecting you to a server and downloading a file by HTTP. Once complete the same file is downloaded as a torrent. The same process is then undertaken for uploads. HTTP traffic is compared to torrent and identifies if your ISP is manipulating or shaping that traffic.

Here is the link: http://broadband.mpi-sws.org/transparency/bttest.php

Note that some ISPs do not throttle all BitTorrent traffic but only if this traffic exceeds a certain threshold and some only Traffic Shape during certain time periods like 03:00pm to 12:00pm.
