My original domain is with Google, I've selected a subdomain (child domain) to be able to create a website on bravenet that would be associated with the parent domain.
You haven't said if the ping results look correct to you.
From what I saw, it is possible that the server at Google is doing what it's supposed to, and the server at Bravenet isn't configured to support the URL it's being sent. Are you sure you have signed up at Bravenet for the service you're expecting?
