Bad news for the Comcast users who seed torrents. TorrentFreak reports that Comcast has started throttling BitTorrent traffic using an application from Sandvine. Sandvine breaks every (seed) connection with new peers after a few seconds if its not a Comcast user. This makes it virtually impossible to seed a file, especially in small swarms without any Comcast users. Some users report that they can still connect to a few peers, but most of the Comcast customers see a significant drop in their upload speed.
