title: Azure App Service - Outbound IPs Changed?
body: <p>I have a site running on an Azure App Service. It connects to a MySQL DB on Google CloudSQL.
  All of a sudden I am getting an error when I hit a page on my site. The error is:</p>
  <p><code>Configuration Error - Reading from the stream has failed.</code></p>
  <p>I know this is related to MySQL and an attempt to read from the DB.
  The DB itself is fine - minimal connections, no stress.
  The site runs fine from my local VS connecting to said database.</p>
  <p>This makes me think I have hit some kind of 'outbound' connection limit on Azure. Can anyone confirm?</p>
  <p>The Azure site is up and running but as soon as it tries to connect to the DB it falls over.</p>
  <p>Thanks for any help you can give!</p>
  <h1>Update - IP Changed??</h1>
  <p>It appears that the App Service outbound IP addresses changed at some point yesterday so our external MySQL DB started blocking the connection attempts. Has anyone experienced this? Every single outbound IP changed. Nothing has been changed on the setup of the app (no scaling etc)</p>
