Here's my theory:

At the border of someone's network there is a gateway that has been set
up to restrict the bandwidth of torrent packets severely.  There is a
community of users that can access the seed without going through that
gateway.  They can access the seed and share chunks at high speed.  The
rest of the world, however, can only see the dribble of data that is
allowed through that gateway.

The only solution is to use another protocol to load a site on the
other side of that (unknown) gateway with a full seed.
