At these numbers, one has to start to count failover time. A system
can be disaster tolerant but take 2 hours to recover fully, or it could
also recover within a couple of seconds. It depends on

I think it's part of the right answer. Capacity and server connectivity

we're already outside our operating envelope
not really. just some folk seem not to understand things such as udp
