I'm planning for the extreme cases by having a redundant server (RAID,
redundant power etc), and soon DHCP failover. I'm *not* planning for
our DHCP infrastructure to cope with 100K requests at once, since I
find such a scenario highly unlikely (even considering the failures
that you have mentioned above).
