I am looking at setting up a geographically separated

the usual reason for geographically dispersed servers is for
lower latency for the local users (eg google has separate
servers for local areas/countries).
You handle failures that must be handled quickly (<1min eg
disks) locally and failures that can be recovered in 24hrs
(eg backup/replication) off-site. Nowadays with RAID etc,
gear doesn't fail a whole lot (except fans which fail about
as often as disks here). Planned maintenance seems to be the
main problem where I am - a bureaucrat insists that security
patches be applied the instant they're released and the
machine rebooted or else we'll be compromised that very day.
Otherwise machines (and nowadays networks) just seem to stay
up forever.
