[CentOS] lftp mirror replication

so I have an internal mirror I was replicating off mirrors.kernel.org 
via lftp, using a script...

     /usr/local/bin/lftp -c 'open ftp://mirrors.kernel.org/pub/ && \
         lcd /export/mirror && \
         mirror --continue --verbose=1 -x ia64 -x s390 -x s390x \
             -x alpha -x SRPMS centos'

well, kernel.org is down now, due to their being hacked, grrrr.   if I 
switch this to another source archive, will it 'just work' or will there 
be any differences in the file dates that will end up causing massive 
new downloads of the same data?

and, is it just me, or is the mirror list on 
http://www.centos.org/modules/tinycontent/index.php?id=30 a lot smaller 
than it used to be?
