OT: Cox slowing torrents?

[Joe]

I'm on Cox cable for internet and paying for their Premiere package 
(20MBit down, 2MBit up). Over the past day or so I've seen my torrent 
uploads go from respectable to abysmal; I'm lucky if I can upload at 
over 10kB/s now. I've reset both my model and router several times and 
that hasn't helped at all. Is anyone else seeing this problem too or is 
it only on my end? Thanks for any feedback.
