 After you add your domain, Cloudflare performs checks on a schedule to confirm you have updated your nameservers. The first check occurs after 60 seconds and the following attempts happen at gradually increased intervals. You can re-trigger the check [via API](/api/resources/zones/subresources/activation_check/methods/trigger/) or on the Dashboard, in the respective domain [Overview page](https://dash.cloudflare.com/?to=/:account/:zone/).
 
+The activation check behavior depends on your zone setup:

 ### Expected behavior for different plans
 
 If your domain is on the Free plan, it will be automatically deleted if it is not activated within 28 days.
