urllib (54, 'Connection reset by peer') error

[Jeff McNeil]

It means your client received a TCP segment with the reset bit sent.
The 'peer' will toss one your way if it determines that a connection
is no longer valid or if it receives a bad sequence number. If I had
to hazard a guess, I'd say it's probably a network device on the
server side trying to stop you from running a mass download
(especially if it's easily repeatable and happens at about the same
byte range).
