title: Azure "successfully starts" deployment, but nothing deployed
body: <p>After performing numerous deployments of some software to Azure, I'm hitting a strange problem which is stopping the deployment from working. (I am doing all these deployments in this case by using Visual Studio's Package command, and then using the Azure portal's Upload button.)</p>
  
  <p>The portal initially says it has successfully started the deployment:</p>

  <p>It also says it is creating the staging deployment:</p>

  <p>But that's all. It never proceeds to show the instance, going through various states and finally running, as has always happened before. There are no further notifications and no error messages. (Even after 24hrs, for the avoidance of doubt.)</p>
