[nbhost]

Hello,

I'm wondering.. if I have one domain name and 4 name servers pointing to it, ns1 and ns2 pointing to one hosting provider while ns3 and ns4 pointing to another provider. If anything happens to the 1st provider (i.e. server down; nameservers up), will my domain resolve to the 2nd provider?

Actually what I want to achieve is have a site hosted on one provider and a mirror hosted on another provider, in case the 1nd goes down.

Thanks.

Yep that should work, however if the users ISP has cached the IPs it will be useless. Just set your DNS zone record to expire every 30 mins to avoid this

No, name servers are not always picked in order, chances are that a random one of the servers would be hit.

I have never heard of this, most ISP lookup the first/primary nameserver before the secondary nameserver.

From my experience it seems to be the case that they are hit randomly.


Try it and see maybe?
