#

The mirror system uses the connecting IP address of the client and the

update status of each mirror to pick mirrors that are updated to and

geographically close to the client. You should use this for CentOS updates

unless you are manually picking other mirrors.

#

If the mirrorlist= does not work for you, as a fall back you can try the

remarked out baseurl= line instead.
