Thanks. I have looked and the server is running fine and could do
another rsync with no trouble. I did see that the route to get to your
server is a completely different one from what you included:

Hi Stephen,
There's actually an rsync running at the moment which is exhibiting the
slowness issue, the sync is happening from from dl03 (209.132.181.25),
and it's showing speeds around 100kB/s. We're connecting from
193.1.219.88.
