My ISP claims to only throttle P2P traffic between 5PM and midnight. Yet, mysteriously, my Bittorrent downloads never go above 1MB/s at any point (be it 4PM or 4AM), despite me paying through the nose for a 60Mb fibre line. Hmmm.
Seriously, I got faster P2P downloads on my crappy old TalkTalk ADSL connection, which was easily half the price -_-
