Go fintech DNS cutovers need separate checks for zone control, record match, and release approval

The article argues that a successful domain verification proves only that someone could publish a requested DNS record, not that a particular person or service is authorized to redirect a payment-facing hostname. It recommends keeping DNS verification, record reconciliation, and release authorization as distinct gates before any cutover. Using a hypothetical payments.example.com release, the author shows how a verification result, an approver's sign-off, and an operator's record change are three separate actions that should not be treated as interchangeable. The piece also notes that domains and personnel change over time, so verification should have a defined freshness policy rather than lasting indefinitely. Finally, it advises retaining both the desired and previously approved record sets, with the rollback target itself approved before the change.
