The network will "only" split if you get errors on your network hardware.
(or fiddle with iptables) Let's say you placed your zookeepers in separate
racks and someone pulls network cable between them - that will leave you
with 5 working servers but they can't reach each other. This is "split

I start out with 5 zk's. All good.
One zk fails - I'm left with four. Are they guaranteed
to split 4/0 or 3/1 - because if they split 2/2 I'm screwed,
right?
Surely to start with 5 zk's (or in fact any odd number - it
could be 21 even), and from a single failure you drop to an
even number - t

Zookeeper requires a majority of servers to be available. For example: Five
