A critical component that ensures websites remain accessible even during failures is Secondary DNS. As you may know, in today’s interconnected world of the internet, reliability and availability are paramount. That is why, in today’s article, we will highlight the importance of this DNS service in providing redundancy and ensuring seamless user experiences.
Understanding DNS Redundancy
DNS (Domain Name System) is the internet’s phonebook, translating domain names (like example.com) into IP addresses (such as 192.0.2.1) that computers use to identify each other on the network. Primary DNS servers are responsible for storing and managing these mappings. However, relying solely on a single Primary DNS server introduces a single point of failure. If this server experiences downtime or becomes unreachable due to network issues, the entire domain’s accessibility can be compromised.
