# How do I change a Faaaster domain's nameservers?

A domain's **Nameservers** section shows the servers that are authoritative for your zone, and lets you change them with **Modify**.

## What they're for

Nameservers decide **who answers** the queries made about your domain. As long as they point to Faaaster, your zone is managed from the **DNS** section. If you delegate them elsewhere — Cloudflare, another host — that's where everything happens.

## Changing them

1. Open the domain from the **Domains** section.
2. Go to **Nameservers**.
3. Click **Modify** and enter the new servers.

> ⚠️ **Propagation can take up to 24 hours.** The interface reminds you of this on screen. During that time, part of the world still queries the old servers, and the rest the new ones.

## What you lose by delegating elsewhere

This is the consequence most often discovered after the fact:

- **the DNS section stops working** — Faaaster displays "DNS records are not available because this domain uses external (non-Gandi) nameservers";
- **email forwarding** stops working, since it relies on MX records managed here;
- any **Faaaster Email service** needs to be reconfigured with the new provider.

> **Delegating your nameservers isn't necessary to use a third-party CDN.** In most cases, a simple CNAME record is enough, and you keep managing your zone at Faaaster.

## Coming back to Faaaster

Re-enter the Faaaster nameservers from the same screen. The **DNS** section becomes available again once propagation is complete.
