Round robin DNS provider

[Hodders]

We have a couple of servers and we want to load balance the traffic between them. We are looking for a DNS hosting company that will let us set up round robin DNS. In addition we would be able to route all traffic to one server in the event of a failure.

Can anybody recommend a supplier ?

At the moment we have a single co-lo server and it hosts it's own DNS. I.e. if the server goes down, all the services go down, so it is no big deal that the DNS goes down.

We are planning to introduce a warm backup server. It will get all the critical data synchronised to it. In teh even t that the 1st server fails, we want to be able to quickly (i.e. short TTL) divert all queries to the second server.

We also want the ability to share some service loading between the two servers. Round robin DNS would let us do that by handing out short TTL DNS results sending some connections to each server.

We could put someking of load balancing hardware in front of both servers but this will be expensive and use up more rackspace. As always we are under budgetry pressure to find a cheaper way of doing it....

So - does anybody know of a round robin DNS host that is any good. For example these guys do it but are they any good ?
