title: Azure DocumentDB - The MAC signature found in the HTTP request is not the same as the computed signature
body: <p>Seemingly randomly I am unable to get a document from DocumentDB. I can be debugging, have it fail with the below message then try again and work. If this has to do with my MAC address i've also tried from a different workstation with the same result.</p>
  
  <blockquote>
    <p>Microsoft.Azure.Documents.UnauthorizedException, message:

  <p>How do I even go about a) reporting this and b) trying to fathom out what's going on?</p>
