title: Google App Engine multiple regions
body: <p>Is it possible for my GAE to be balanced accross regions? Like US and Europe.<br>
  <a href="https://cloud.google.com/about/locations/" rel="noreferrer">https://cloud.google.com/about/locations/</a><br>
  Reading the link above it says that it scales automatically within or accross multi-regional locations.<br>
  What does that mean? Do I have to enable automatic scaling across regions? If so, how do I do that?<br>
  And secondly, if it does handle automatic scaling across regions, the choice one makes for <code>App engine location</code> when creating a new project, is that irrelevant for a Google App Engine instance?</p>
