I know its well known that BT do traffic shaping, but it doesn't affect me. What i'm curious about is that it is widely (not sure on this but its what i've seen here) accepted that they blanket cap upload speeds on torrents to ~130KB/s. Now thats what i've observed too for most of the time, but then theres the odd time that my upload speed gets fully utilized (currently been going at about 1MB/s for half an hour now). I can count those occurrences on one hand but i'm wondering whats the reason theres suddenly no cap on the up speeds?

Aye.
Thing is with BT throttling, its somewhat dynamic and not very uniform in useage i.e. if the system detects high useage levels in the overall network then P2P will get clamped down on even if you haven't exceeded the FUP. I'm not sure if they are currently running P2P restrictions on people who aren't exceeding the FUP but typically you might see say uncapped from 2am to 6am, 2Mbit cap from 6am til 6pm, 128kbit cap 6pm til midnight and 2Mbit cap from midnight til 2am. But say the world cup was on and there was a game at 4pm then you'd see P2P pulled down to say 40kbit/s during that time and 128Kbit for 2 hours either side.
Another thing they used to do - not sure if its still in affect with 21CN and the new traffic/best effort classes - if your exchange was heavily loaded then you might see P2P restrictions through out most of the day and even as low as 20kbit during peak times.

P2P restrictions apply 4pm-12pm weekdays and 9am-12pm weekends regardless of FUP
