DNS Failover Questions...
How can you implement DNS Failover on your own? I mean, using your own 2 dedicated servers and not getting outside help (outside DNS Servers)?
We tried modifying the nameservers of our domain to ns1.original.com and ns2.backup.com.
We tested it, when the original server went down, the 2nd server or backup server took place.
But the problem is that when we put up the first server, and you go to the site, it still being pointed on the 2nd Server. How can you bring it back to the first server?
What are the DNS Zone Setup do we need? for both servers?
And how actually is Round-robin works?
Thanks in advance.
