Thanks

Re: what is a DNS cluster?
DNS Clustering is using multiple name servers that share the same records, located in different geographic areas to serve your DNS records.
Advantages of a DNS Cluster :
1. Downtime is 0% due to DNS service being down. If the DNS service is down in the server, the domain DNS will be supplied by the other servers in the cluster.
2. No delivery failure: If a server is down (say being rebooted), and at that point if someone tries to send an email to a domain on that server, they will get a delivery failure message and the mail will not be sent again. This is because the senders’ mail server will assume the domain does not exist. But in case a DNS cluster is setup, the mail server sending the mail will only assume the mail server is down, and hold the mail in its queue to be retried again.
3. It is easy to transfer domains among servers. The client will not have to change the name servers used by the domains. The same name servers can be used to point the domain to the new server.
4. You can use Global name servers for all your servers. No need to set specific name servers for each server.
DNS clustering together with Load balancing will definitely give you the fastest performing servers with absolutely no downtime at all.

A DNS cluster is a number of name servers that share records. This allocates us to physically divide our name servers. This way, clients can reach our websites on server more quickly.

Re: what is a DNS cluster?
A DNS cluster is a collection of nameservers that share records, allowing you to physically segregate the DNS servers from your web servers. You can use this interface to set up a DNS cluster and add servers to an existing DNS cluster.
How it's works
DNS cluster is a service that consists of a number of name servers that share records with one another. It permits domain name queries to be handled by different nameservers from web servers. Visitors will be able to access webpages on your server more rapidly after it is back online in this manner.

Re: what is a DNS cluster?
The Domain Name System includes nameservers. These DNS servers store information about which domains are linked to which IP addresses. Nameservers allow us to utilise a domain instead of the DNS server's IP address.
Clustered DNS A DNS cluster is a collection of Nameservers that exchange DNS records. DNS cluster has the advantage of physically separating the nameserver that handles DNS requests from the webserver. With the addition of extra Nameservers, the service's downtime is reduced.
