title: Whats the status of External Master Replication beta in Google Cloud SQL
body: <p>I have a compute image that is running a mySql database, with confirmed access to the outside world.</p>
  
  <p>When using the curl script to create an 'interface' to this database no errors are returned. However in the console GUI there is a warning triangle and no read replica can be created. </p>
  
  <p>Are there any known issues with this functionality and/or are there any ways that I could get out some more logging in the response?</p>
