Knowledge Base & Operational DocumentationHow to Review DNS Changes Before Retiring an Old Hosting Account
11/10/2026
An old account may still serve subdomains, mail, verification files, or scheduled integrations after the main website moves.
Checks to make
Inventory authoritative records, traffic and mail logs, certificates, and application dependencies. Confirm each hostname has a target, lower TTL before planned changes, and keep the old service until monitoring shows no required traffic.
When to get help
DNS and hosting support can map residual dependencies before decommissioning. Informatix Systems can assess the symptoms, evidence, and next steps. Contact Informatix Systems to discuss this issue.
