Hi,
The issue started around 1 pm UTC!
My application is hosted on: Region: europe-west2
I had the same issue also on another application that is hosted on Region: us-central, but around 2 hours ago it was fixed.
The error that I received is this one:
java.lang.RuntimeException: Fatal problem encountered during deployment. Please refer to the logs for more information.
Unable to update app: Fatal problem encountered during deployment. Please refer to the logs for more information.
Please see the logs [/tmp/appcfg686702965770461882.log] for further information.
Here is a part of the error from the file (also in the attachment)
com.google.appengine.tools.admin.AdminException: Unable to update app: Fatal problem encountered during deployment. Please refer to the logs for more information.

Now everything is OK with the deploys on us-central, but for the ones on europe-west2 I receive error every time! (after around 10 minutes of verifications)
