I would like to fallback to a static webpage if my main web server is down (currently a Rackspace Cloud instance). This would be a sort of worse-case scenario that shouldn't happen, but has before (e.g. Backspace hardware failure). Redundancy of the servers would be an optimal solution, but budget is a concern.. so I'm looking to a low cost autoMatic fallback if something happens to the only server currently
Answer
Unless you have some sort of second server using a DNS round-robin setup then I'd suggest you speak with rackspace to see if there's a load-balancer in front of your server that can routinely check for service availability and redirect requests elsewhere upon an outage.
Basically there's nothing you can do with a single server as obviously your service outage may be due to total loss of the server, so it needs to be driven externally.
