Same happened to me and I'm signed up with Tiscali - I was downloading at roughly 25-30kB/s when I first installed bittornado about a week or so ago. It's all of a sudden gone down to 5-6kB/s
It's only when downloading with bittorrent that the connection seems to be slowed. I've downloaded stuff using DAP and I get the usual 25-30kB/s. When I've tested my download speed at
http://www.adslguide.org.uk/tools/speedtest.asp and got more or less what I expected:
Downstream 232 Kbps (29.0 KB/sec)
Upstream 44 Kbps (5.5 KB/sec)
So Tiscali are capping me when I use bittorrent
I think I'm probably going to go down the same route as Michelle and look for a different ISP unless by some miracle I come across a solution.
Thanks for the links Michelle - I'm gonna check them out.
