Hmm, how are they interconnected?

A simple DNS scheme _could_ be enough for your system (and it may not
be). Just enter more than one IP-address for your domain, and it will
rotate between the two server. Remember to set a quite low TTL.

The cheap solution:

        Keep a low TTL and be fast to remove the ip-adress of the
        malfunctioning server when it goes down.

The semi-cheap solution:

        Does the same as the cheap solution, but automates it.

The "good" solution:

        Normally requires the two servers to be located the same
        place, or have a good redundant connections to each other.
