Gah.  Clearly, I didn't completely read your original email.  Sorry
about that.  This error originates inside urllib2 and is associated
with a name not resolving.  I'm with Greg that it appears to be
temporary network issues, such as name resolution or DNS access.

Another test is that you could push /etc/hosts files to your machines
to see if that helps.
