Let me show you a very simple way to improve your website’swebsite’s reliability – Anycast DNS. You can have multiple DNS servers with the same IP address and speed up your domain resolution greatly. Here is how.
Why should you care about DNS?
DNS is the system that makes it easy for all of us to use the Internet. It translates the domain names to their IP addresses. That way, it distributes queries to the right places. For example, if you search for Google.com, your browser will have the task of using DNS to search for the correct DNS server and find the IP address of Google so that you can connect to it. In a traditional scenario, a single Primary DNS server will answer all queries for a domain name. But you can improve that by having multiple servers which can answer the query. So here comes the Anycast DNS.
