Summary

Secondary DNS is a crucial aspect of Domain Name System (DNS) infrastructure that provides redundancy and reliability by maintaining a read-only replica of DNS records from primary nameservers. This helps prevent service disruptions in case the primary server goes down or experiences an outage. As businesses scale their DNS infrastructure, they often move away from on-premise servers to managed DNS providers and multiple DNS vendors for increased redundancy against potential attacks. Cloudflare's Secondary DNS product offers a seamless experience with its new onboarding UI, allowing customers to configure their zone in just a few clicks. Additionally, secondary DNS customers can benefit from the same DNS analytics provided to authoritative DNS customers.
