[CentOS-mirror] Rsync Error

When trying to sync form us-msync.centos.org today, twice we have gotten errors about the max connections being reached. Are there peak times for the master servers that we might be able to avoid when pulling our updates? Better yet, is there a graph or any other automatically updated means whereby we can check the connection count's or bandwidth usage of the main servers so that any admins running a CentOS mirror can look at and figure out for ourselves when to best mirror the repos?

I'm getting the following error when I try to get updates. @ERROR: max connections (40) reached -- try again later
