If your servers can't communicate with each other how would you
prevent multiple people from updating the *same* part of the
dataset during the outage?  And even supposing for some reason
that was ok, once the network connections came back, how would
the servers decide which one had the correct version that should
then be replicated to the others?

These are the issues you have to solve if you want replicated r/w.
