Created Unassigned: The application is offline deployed in Windows Azure [1685]

I have done the steps of this walkthrough: Host your Composite C1 website on Windows Azure http://docs.composite.net/WindowsAzure/Setup/Simple-Site

And I received the following message: The application is offline

Deployed locally I am able to remove the app_offline.htm file located in App_Data\Composite, but how about in Azure deployments?

I have followed exactly the walkthrough and it doesn't tells nothing about it

Any idea?
