Now the fact that one IP went down is not reflected in DNS
That is bad. Isn't it possible for you to update then DNS entry
triggered by a kind of heartbeat from the servers?
If you then also set the TLL on DNS side to a low value (say, 1min or
so), the clients get in most cases a working IP ...
Finally, what you want is not only load-balancing by DNS, but also a
kind of high-availability...
You have the choice:
* do it on client side by querying the DNS for all IP adresses and let
the client choose one of them
* do it on server side by setting TTL on DNS to a low value + remote
dead IP entries in DNS
