Rogers has stomped on tons of BT traffic, which encryption no longer helps with (well it helps but not much), nor does changing your port number used. Sounds like they just rolled that out in your area ... in my area has been pretty much useless for a while now. Downloading completely legal torrents for me I was connecting to hundreds of peers and seeds and getting 20k/sec max download speed, even though I was seeing swarm speeds of megabits/second.
Rogers sucks for this. I've complaiined to them numerous times and all they do is point out that they are simply shaping the bandwidth to provide best results for everyone (everyone except people using BT apparently). Having to download 3-4 gigs of stuff for a linux distro through BT is so painful it's not funny now.
Not only that, but when they are "filtering" me as mentioned above ALL of my access crawls almost to a halt. When I mentioned this to them they simply said "then don't use bit torrent" ... and this came from someone much higher up than teir 1 (or 2) tech support.
To me this is like Bell saying "you can't talk about _____, and when you do your conversations will suddenly cut out or sound very poor. If you don't want to experience this, don't talk about _____."
The same has been happening here (Waterloo, ON). Using Azureus, with encryption, BT speeds have gone down the crapper. Rogers service of late has been dismal. First major DNS issue, then today our entire neighbourhood lost service. Amen I'm a renting student and will be back with Bell come spring. Apparently Teksavvy is pretty sweet from what friends have been telling me. No port blocking, filtering, shaping, etc.
