Evidence before action
Choose the next useful path
Diagnose from evidence
Start with the symptom, inspect without changing state, and identify the system owner responsible.
Change with a rollback
Use preflight, ordered changes, verification, stop conditions, and a tested path back.
Troubleshoot now
Start from a common symptom
A name returns NXDOMAIN
Separate an absent name from NODATA, negative caching, and delegation trouble.
The website broke after a nameserver change
Check parent delegation, authoritative data, DNSSEC, caches, and the web path in order.
The website works but email fails
Inspect MX routing, exchanger addresses, SMTP, mailboxes, and sender authentication separately.
