Setup a server failover.

I have a tendency to tinker with my server and cause unplanned outages, so I'd like to set up some sort of failover for my Amazon EC2 instance that will re-reroute to my home IP address. After the downtime is over, I'd like it to automatically route back to the original server.

I tried setting up a Load Balancer in my AWS panel, but it doesn't appear that this is my solution.
