Why DNS Needs to Be Treated as Critical Infrastructure
DevOps.com, Wednesday, September 23rd, 2026
DNS is core infrastructure that needs formal change management, tested redundancy, and strict access controls.
DNS is often ignored until it breaks, yet it underpins app connectivity, email, identity, and cloud workloads.
The article argues organizations need formal change-management processes for DNS edits, since a single record change can have a wide blast radius. It calls for actively tested secondary DNS and failover, regular audits against DHCP/IPAM/asset inventories to prevent DNS drift, and least-privilege write access to zones.
The overall message: DNS deserves the same governance and visibility as other critical infrastructure.
