If either box goes down, the other box takes over the HA address. Requests are round-robin routed to the HA addresses using a pair of routers (and that part of it the configuration is beyond me). Every (good) OS has an implementation of HA IP addresses. We use FreeBSD, which offers CARP [1] as a solution.
