DNS Changes to Review Before Launch Day

What to check before changing DNS records for a new website, email provider, CDN, or hosting environment.

Overview

DNS changes control where a domain sends web, email, and verification traffic. Reviewing records before launch helps prevent downtime.

When this helps

Use this article when launching a redesigned site, changing hosts, connecting email, adding SSL, or moving DNS management.

Recommended steps

  1. Identify where DNS is currently managed.
  2. Export or screenshot existing records before making changes.
  3. Separate website records from email records so mail is not disrupted.
  4. Lower TTL values ahead of planned changes when possible.
  5. Test the new website and email flow after DNS propagates.

Information XMLA may need

  • Registrar login or DNS manager access
  • Current A, CNAME, MX, TXT, and SPF records
  • Launch target IP or host value
  • Email provider details
  • Preferred launch window

Next step

Send XMLA DNS access before launch day so records can be reviewed before any public change is made.
