It's total loosing the purpose of "throttling P2P", when the management started to apply. I can't even open up google's home page! take 10 minutes to load the youtube home page!
The only one benefits from this policy is Virgin Media, because they don't want to invest in scaling up their infrastructure in order to handle large traffic, instead, they cut meat from their lovely users with a shitty software to cut down cost.
BTW, this shitty software is probably introduced by some PhD or stupid professors as half done research project - seems smart but shitty algorithms.
