#
# This file uses a new mirrorlist system developed by Lance Davis for CentOS.
# The Mirror system uses the connecting IP address of the client and the
# Update status of each mirror to pick mirrors, are updated to and
# Geographically close to the client. You are should use this for CentOS updates
# Unless you are manually picking the other mirrors.
#
# If The mirrorlist= does not work for your, as a fall back you can try the
# remarked out Baseurl= line instead.
