DNS & Nameserver Fix
Repairing broken DNS zone files, resolving MX/TXT/CNAME routing errors, migrating domain registers, and implementing security SPF, DKIM, and DMARC parameters for reliable email delivery operations.
Execution SOP & Action Plan
Every emergency intervention follows a strict sequence of diagnostics, mitigation checkpoints, and verification tasks to guarantee stability and prevent regressions:
1. Zone File Audit
Export full DNS zone; verify A, CNAME, MX, TXT (SPF/DKIM/DMARC), and NS records against domain registrar; use dig +trace to confirm propagation path.
2. Record Correction & Propagation
Update broken records at registrar/Cloudflare; set TTL to 300s for fast propagation; confirm changes via nslookup from multiple geographic nodes.
3. Email Deliverability Hardening
Create/validate SPF TXT record, DKIM key pair in cPanel/mail server, and DMARC p=none policy record; send test mail through Mail-Tester.com.
4. Full Propagation Verification
Use whatsmydns.net to confirm global DNS propagation; verify mail flow end-to-end; restore TTL to 3600s after successful validation.
