With DNS round-robin your users will complain whene either one of IP

This is not such a huge issue when you do the "round-robin" with very

still does that.
Do you mean providing different DNS record when one of servers is down?
I mean, providing multiple IP addresses: clients that first try to
connect to address that is down will complain that the connection takes too
long.
