Possible but unlikely. My modem is 6 months old. ive been using utorrent without any issues with maximum 100 peers without any issues until 3 days ago, my speed crawls at <10kb/s. Ive tried to change ports, lower the bt.connect_speed and increased and lower the net.max_halfopen values. After restarting my modem, the speed was ~50kb/s for about 5-10mins then drops down to <10kb/s. The result was same with the other pcs in my home. was using utorrent 3.1.3. I tried updating it to 3.3 but the results still remain the same.
I then tried out Bitcomet and the problem was solved. However, it couldn't connect to the trackers and rely on DHT and peerexchange to obtain peers. but once it manage to get adequate peers, the speed gradually rose to 400-500kb/s. Im not using a proxy to connect to the trackers. I am not sure is trackers were being blocked or the connections to the trackers were poor due to the SEA-ME-WE 4 cable damage.
Bitcomet are banned in most trackers because most of bitcomet user and bitcomet itself is hit-run type and this is bad for every torrent community, that might be the answer why your bitcomet unable to connect to the trackers.
Anyway, I wasn't trying to guide you to speed up your torrents download, I'm just saying lots of connection is bad for your network since it will slow down everyone else devices. 20 connection is more than enough for common 4Mbps connection.
Back to throttling, there's no connection between damaged cable or anything else, it's just system glitch which allows you to temporarily bypass the throttling system, it was unclear due to what, so far as long you keep your connection on, there's a chance you'll accidentally bypass the throttling.
