retrieving "owner/viwer" information is not working for past couple of days in orkut/igoogle/gmail apps

Question

This is something that I have noticed the retrieving "owner/viwer" information is not working for past couple of days. Here is the code that can demonstrates the same:

  <script type="text/os-data" xmlns:os="http://ns.opensocial.org/2008/markup"&gt;    
    <os:OwnerRequest key="owner" fields="name"/>
  </script>

  <script type="text/os-template" require="owner" xmlns:os="http://ns.opensocial.org/2008/markup" xmlns:osx= "http://ns.opensocial.org/2009/extensions"&gt;

    This app belongs to ${owner.name.familyName}
  </script>
