1. Go to **Magic Transit** > **Configuration**.

:::note
Withdrawing a prefix should propagate across Cloudflare's global network almost instantly, with changes typically taking effect within a few minutes at most. However, Cloudflare has no control over how long ISPs take to refresh their routes. Keep this in mind when announcing or withdrawing a prefix from your account, and plan accordingly.
