Check these first
- Domain registration is active and not expired.
- Nameservers at the registrar match the intended DNS host.
- A, AAAA, CNAME, MX, TXT, SPF, DKIM, and DMARC records still exist.
- Recent DNS edits, hosting moves, or registrar changes are documented.
- TTL and propagation explain timing, not a permanent misconfiguration.
