I've just set a new server up at our ISP - on three backbones to cope with network outages. The A record for the host has all three IP addresses... so that presumably any client will choose one at random and then try the others if the connect fails. This is all very well - but it also means that the client may not be taking the most direct route to our host. Is there any way to make the client try the shortest route first.. and is this even desirable? I seems to be something that should happen for efficiency's sake but I have no clue if it's possible. My concern is that on one occasion a client will see a fast throughput because the closest address was chosen - but on another will see poor response because his resolver chose another address that got routed via Outer Mongolia or somewhere equally far away. Thanks in advance for any input.
