How to Diagnose a Website That Returns an Error After a DNS Failover

Failover can direct users to a secondary host with stale content, missing configuration, or an incomplete dependency.

Checks to make

Compare DNS answers and TTLs, test both endpoints directly with the intended hostname, and review health-check and replication status. Confirm certificates, data consistency, and external dependencies before treating the secondary host as ready.

When to get help

Hosting support can trace failover readiness across DNS and origin services. Informatix Systems can assess the symptoms, evidence, and next steps. Contact Informatix Systems to discuss this issue.
