Up until thispast month, I've had no problems downloading torrent files using uTorrent. Now, nether magnet links nor .torrentfiles can download. Is it possiible that hte ISP has startd blockingP2 P traffic.? Is there a way to detect this? ( I mean finding out yourself and not asking the ISP directly. Would that even work?)

find out from your ISP –  pratnala Nov 20 '12 at 6:45
Enable encryption. ISP can only block traffic they known. I will bet this is a routing problem as almost no ISP completely cuts torrent traffic. –  Mikhail Nov 20 '12 at 6:52

you can port blocking from your isp with this site:

What is my ip - Port Scanner

but you can randomize port of torrent client that cause bypass specific port blocking from isp.

This doesn't work anymore as network monitoring software has incorporated learning algorithms into its detection strategy.. –  Gabriel Fair Sep 13 at 16:57
