  8. # The mirror system uses the connecting IP address of the client and the
  9. # update status of each mirror to pick mirrors that are updated to and
  10. # geographically close to the client.  You should use this for CentOS updates
  11. # unless you are manually picking other mirrors.
  12. #
  13. # If the mirrorlist= does not work for you, as a fall back you can try the
  14. # remarked out baseurl= line instead.
