Best Practices

Best Practices is the compact operating standard for safe, traceable, and recoverable SDM administration.

What this page does

These habits reduce the most common causes of DNS outages: wrong scope, stale state, missing delegation work, unsafe DNSSEC order, broad provider actions, shared credentials, and unverified restores.

Before you start

Adapt change windows, retention, and approval steps to your organization. Do not weaken identity or safety controls merely because a task is urgent.

Operating standard

1. Use named human accounts and dedicated integration identities; never share root or provider secrets.
2. Enable 2FA for people and use separate panel/API IP rules.
3. Read current zone, owner, provider, DNSSEC, and delegation state before writing.
4. Make one bounded change, preserve a backup, and keep rollback criteria.
5. Use exact confirmations for zone/provider deletion and DNSSEC disablement.
6. For DNSSEC, follow parent-first disablement and staged rollover checkpoints.
7. For Cloudflare, distinguish desired provider, active provider, synchronization, and public delegation.
8. Keep cluster-wide and node-local settings in their proper pages.
9. Use realistic monitor thresholds, tested recipients, and conservative automatic actions.
10. Verify with authoritative and public DNS, then correlate Audit and Logs.
11. Test restores periodically; an untested backup is a hopeful file collection.
12. Keep public API clients on port 882 and document every parameter in their own integration runbook.

How to use it

1. Turn the standard into a pre-change checklist.
2. Assign the owner, target, expected result, verification, and rollback.
3. Perform the change through the owning page or public API operation.
4. Collect proof and close the change only after downstream verification.
5. Update local runbooks when the environment-specific lesson is reusable.

Result and next check

SDM work is attributable, least-privileged, reversible where possible, and verified at the layer customers actually use. That is what “done” means for DNS.
