No sorry, I don't know of any mirror site.  Yours is the first report I have
seen of a slow FTP connection to our site.  We have a high-bandwidth
connection to the Internet.  I suspect you are seeing symptoms of a
temporary problem and that you will have better luck trying it at some other
time.

I just tried to ping to another host in Deutschland with a netCDF user on
our mailing list and it indicates fairly high packet loss:

  % ping -s kirk.es.go.dlr.de

A "traceroute" shows me the problem is not local, but a problem in routing
packets somewhere "out there", perhaps the routing hop in the Atlantic link.
