yum on Centos stuck at "loaded plugins: fastestmirror"
===

When trying to install a package using yum on Centos, the command is getting stuck at the first part:

    loaded plugins: fastestmirror

I've tried:

 1. removing /var/cache/yum/timedhosts.txt
 2. yum update yum
 3. making sure there are no other processes running and removing /var/run/yum.pid
 4. yum clean all


... still having the problem.

Any ideas?
