It's stated in the documentation that it's possible:
If you have an App Engine Premier account, you can specify that your new application should reside in the European Union rather than the United States. For developers that do not have a Premier account, you will need to enable billing for applications that should reside in the European Union. https://developers.google.com/appengine/docs/python/gettingstartedpython27/uploading But you can't set up billing without creating the application first, and when the application is created you can't edit the location, so either isn't is possible for non-Premier accounts to create apps in the EU or I need a step by step guide on how to activate billing before creating the app. -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
