title: Azure role being queried (GET /) every 5 minutes from Microsoft IP address
body: <p>In one of our Azure roles we have a log that is accumulating a lot of HTTP 404 errors as a result of regular HTTP requests (Get / ) coming from an IP address belonging to MS.  </p>
  
  <p>Is this "traffic" part of the Azure role health monitoring?  We don't have a controller/action to respond to that request.  I would prefer not to open that door unnecessarily, but if I could unambiguously identify it as Azure health monitoring, then I could at least filter them out when logging.   </p>
