What happens to old DNS records when you connect a domain

When you connect a custom domain and turn a Turtini site on for it, the old website at that hostname has to stop serving — otherwise the domain keeps resolving to your previous host. Turtini handles the cutover for you.

What gets removed:
At the exact hostname you connect, Turtini automatically deletes the OLD website-hosting DNS records — the A, AAAA, and CNAME records pointing at your previous host (HubSpot, Squarespace, Wix, a Salesforce Site, etc.). Once those are gone, the old site stops serving and the domain points only at Turtini.

What gets left alone — on purpose:
• **TXT records** — domain-verification tokens and SPF stay, so HubSpot/Salesforce domain verification keeps working
• **MX records** — email routing is untouched; your mail keeps flowing
• **NS, CAA, SRV records** — nameserver delegation, certificate-authority rules, and service locators are all preserved

The connect dialog shows exactly which records it cleared, so there's no guessing about what changed. If you ever need them back, re-add the records in your DNS provider — Turtini only removed the hostname-specific website records, nothing else.
