[Nottingham] DNS question for specifying redundant servers

[Martin]

>From discussions last night...


OK, so how is this done in general?...

You have multiple servers dotted around the country/world with different
internet addresses. So how do you set the DNS for the world such that
normally only one server takes all the load but one of the others picks
up all the load if the first should fail? And thence, the third picks up
the load if the second should fail?

Or is this never done this way?

If you have the DNS give (round-robin?) multiple addressing for the
three servers, what happens if one or two fail in that case?

Answers for mail servers and web servers please...

Cheers,
Martin
