When a server name is solved to different IPs, the client has to handle that. I mean, the client would get the list, and try one by one. It is not an actual health check, and the service might look ok (accepting connection on port 80/443) when they are not ready to handle requests.\n\nMoreover, I am not sure if the IP list returned by the DNS server could rotate somehow based on load (or other factors).
