Knowledge Base & Operational DocumentationHow to Review DNS Changes Before Switching a Website to a New CDN
11/10/2026
A CDN cutover changes proxy behavior, origin requests, TLS termination, cache rules, and possibly DNS validation paths.
Checks to make
Inventory hostnames and DNS records, confirm the CDN can reach the origin, verify certificates and cache bypass rules, and test dynamic and authenticated routes. Plan TTL and rollback, then monitor origin load and errors after switching traffic.
When to get help
DNS and hosting support can plan CDN cutover and origin validation. Informatix Systems can assess the symptoms, evidence, and next steps. Contact Informatix Systems to discuss this issue.
