Connect the server(s) to APC MasterSwitch or equivalent hardware. Monitor 
the server box(es) for responsiveness. If/when it fails, the monitoring 
station can instruct the MasterSwitch to reboot (power cycle, really) the 
box. Stuff is pretty inexpensive (certainly less so than load balancers).

My initial thought last night was in fact the use of load balancers. But 
then you need to think about redundant load balancers and so on.
