There _is_ a way to set up a secondary IP address in the DNS, but while
FTP and telnet will use this, I have NEVER seen a web browser that supports
You could set up a second machine on the same network that would 'ping' the
unreliable machine, and if the other machine goes down, either take over it's
IP address, or better, trip a relay and reboot it.
Of course, a better solution is to just replace the unreliable connection
I have set up mirror sites for several people, but usually this is in
addition to the regular site, and you'd have to tell your users to try the
alternative sites if the first one fails.
