I basically want to have mirror sites set up on a different network in case the main one fails. What is the best way to do this? I would like to try it out with one of our servers that has roughly 140 domains on it. When the server goes down, it automatically kicks it to the other, backup server where the backups of sites are . Do I just use DNS and set up 2 different nameservers/IPs?
Thank you for your help.
