Hello, I have 2 servers. How do I setup the DSN for these 2 servers with my domain? For example, I have domain "mydomain.com" and server1 and server2. I want ns1.mydomain.com, ns2.mydomain.com --> server1 ns3.mydomain.com, ns4.mydomain.com --> server2 Both server installed cPanel/WHM. Thanks!

you would need to setup subdomains in the zone file for each of the servers. If however you are talking about if this fails, choose that: that is not somethign controlled by DNS.

Hi asoduk, thanks for your response, My current setup is like this: - In my domain control I set the DNS Name of mydomain.com to: ns1.mydomain.com ns2.mydomain.com ns3.mydomain.com ns4.mydomain.com - DNS Zone of server 1: DOMAIN--------------RecordType mydomain.com. -------NS------------ns1.mydomain.com mydomain.com. -------NS------------ns2.mydomain.com alpha ----------------------A-------------xxx.xx.xxx.60 ns1.mydomain.com. ----A-------------xxx.xx.xxx.60 ns2.mydomain.com. ----A-------------xxx.xx.xxx.61 beta-----------------------A-------------yyy.yy.yyy.80 ns3.mydomain.com. ----A-------------yyy.yy.yyy.80 ns4.mydomain.com. ----A-------------yyy.yy.yyy.81 - DNS Zone of server 2: beta.mydomain.com. -------NS------------ns2.mydomain.com beta.mydomain.com. -------NS------------ns3.mydomain.com It works fine, but my question is that if server 1 went down, would server 2 down too?

Do you use database on the website? Any replication between 2 servers? I would say if the dns resolve is already cached, the website will be down. If dns is not cached, 50-50 chance that the website is not accessible.
