So when the failover kicks in, the deadly requests gets moved to another server which it can then bring down in turn. Get the timing Just Right and by The Time The First Server Has Rebooted, IT Will Be Ready To Receive That Request Again.

A person, or even a group of people, can never get a design through BDUF, because a very good stuff, actually use it, often has completely unexpected results. So, there is no existence of all ENOUGH Design.
