What happens if you run "curl http://mirrorlist.centos.org/"?  I see this:

$ curl http://mirrorlist.centos.org/
arch not specified

Test that, and then use curl on some other url.  "curl 
http://www.google.com/" maybe.

This should establish whether or not you have general network 
connectivity.   Either way, you'll probably want to talk to your network 
admins regarding the result.
