They might have a contractual responsibility for extremely wide
geographic distribution.  Or they might be building an application
that needs extremely wide network-topological distribution to avoid
large loads on any one network.  For instance, I can imagine building
a network of nameservers in which you peered the nameservers,
colocated in every ISP you could think of.  If you were backing the
nameserver with Postgres, this would work.  To be clear, this is _not_
the case with any product I've ever built, but it is a design I have
seen deployed.  That design was supposed to be on top of Oracle.
There were well over 50 slaves.  I don't really believe they had that
many Oracle-using slaves, though.
