Sites Not Reachable After Linode Restart

I have recently moved the majority of my sites over to my CentOS Linode VPS and I was experience some load issues that prevented me from gaining SSH access.  As such, I decided to restart my VPS.  After the restart, I found that my sites were not reachable…lame.

/etc/init.d/network restart

A simple edit to the above file and a quick network restart solved my problem and brought my sites back up! w00t!
