Multiple DNS Alias (CNAME) with same name

We currently have a DNS Alias (CNAME) record called Company which points to myserver.domain.co.uk. I want to create another Alias (CNAME) called Company, but points to myserver2.domain.co.uk. This is for redundancy.

Of course, if I do this I get an error back saying there is a conflict, and the current Alias (CNAME) will get deleted.

Is what I'm trying to achieve possible?

Not out of the box that I am aware of.  There are products that will allow for failover of dns aliases such as doubletake.  If anyone knows a work around for this I could use it too :)

weighted DNS records are only available in MX records (for email servers)

there are sever methods of achieving the result your looking for though,

one way is with a router that will redirect a external IP address to a internal failover, Barracuda and Cisco have these kind of routers for example.

another way is using your own DNS servers. DNS servers can have a list of forwarders so basically you set up a DNS server that forwards it's requests to another DNS server that is ALSO your web server and it lists itself as the address for that A record. IF that server is off the first DNS server will use it's SECOND forwarder, which is ALSO a DNS server that lists itself as the A record for that address, etc....
