title: Azure returns 503, but access logs report 200
body: <p>I'm encountering some weird behaviour on my Azure website. We poll a test action regularly. In our tests we record several 503s. When I correlate the reported times to the Azure access logs I see a status code of 200 in the Azure access logs, with a particularly long request processing time ~24 seconds.</p>
  
  <p>Has anyone encountered this? Could it be that the website VM returns the request, but a time out period set by Azure has already passed so it has returned 503 to the client?</p>
  
  <p>Any help would be greatly appreciated!</p>
