title: Intermittently getting 404 error, "Owner resource does not exist"
body: <p>We just started noticing this yesterday as we added code to our system that automatically manages databases and collections. Previously, we created them manually through portal.azure.com. So we are running lots of tests, creating and deleting both databases and collections many times during the tests.</p>
  
  <p>Intermittently, we get a 404 error with this message, "Owner resource does not exist", maybe once out of every 10 times we run our tests.</p>
  
  <p>Also, in the same tests we also get the error, "The MAC signature found in the HTTP request is not the same as the computed signature". That happened twice yesterday but none today.</p>
  
  <p>We are running these tests in US East.</p>
