The wiki page says: """ NOTE: To provide fastest access to public mirrors, we have now restricted access (at the IP level) for known public mirrors (see http://lists.centos.org/pipermail/centos-mirror-announce/2014-June/000015.html). So for your first synchronization, you should use one of the external mirrors providing rsync access. You can find that list here: http://centos.org/download/mirrors/ """ So, sync first from some other public mirror. Once your mirror is ready (as in, it has all the content), you can request to have your mirror added to the list. At that point you will get access to sync directly from msync.centos.org.
