Hi there

Also, if you use DNS round robin, clients will still try to connect to the "downed" server... For example, if I had DNS set up with two A entries for 10.0.0.1 and 10.0.0.2 and 10.0.0.2 goes down, clients will still try to connect to it 50% of the time; what's worse is that, since its cached, they'll continue trying to hit it.

Set the TTL of the records to a short time (a few seconds). Remove a downed API node from the round robin record (you could do this automatically).
