I think they are trying to track the downloads by using some kind of
redirection. Perhaps the final source is having problems.

Look how it redirects to a different address and stalls every time:

The source will eventually close the connection and wget will retry and fail
(because the download session ID doesn't exist anymore ? hit a different
