Solution

1. Check if the fastestmirror plugin is enabled:

   # grep -n 'enabled' /etc/yum/pluginconf.d/fastestmirror.conf
   /etc/yum/pluginconf.d/fastestmirror.conf:2:enabled=1

2. Make sure the mirror being used is reachable locally and from other test servers. If that's not the case, exclude it in the "fastestmirror.conf" file:

   # echo "exclude=$MIRROR" >> /etc/yum/pluginconf.d/fastestmirror.conf

Cause

Unreachable mirror.
