 * You can update any of the endpoints supported in your service tier. Typically, customers update **Gateway** (this URL is used to call the APIs exposed through API Management) and **Developer portal** (the developer portal URL).
-* The default **Gateway** endpoint also is available after you configure a custom Gateway domain name. For other API Management endpoints (such as **Developer portal**) that you configure with a custom domain name, the default endpoint is no longer available.
+* The default **Gateway** endpoint remains available after you configure a custom Gateway domain name and cannot be deleted. For other API Management endpoints (such as **Developer portal**) that you configure with a custom domain name, the default endpoint is no longer available.
 * Only API Management instance owners can use **Management** and **SCM** endpoints internally. These endpoints are less frequently assigned a custom domain name.
 * The **Premium** and **Developer** tiers support setting multiple hostnames for the **Gateway** endpoint.
 * Wildcard domain names, like `*.contoso.com`, are supported in all tiers except the Consumption tier. A specific subdomain certificate (for example, api.contoso.com) would take precedence over a wildcard certificate (*.contoso.com) for requests to api.contoso.com.
