Hi Adam, This was a working app that stopped working all of a sudden. We raised a ticket with Google and have now sorted it out. It seems Google is bringing security constraints for Apps so that when using the Google Mysql Driver, you have to specify the db address as projectid:instanceid and not the IP address. This rule was enabled on our app at mid day yesterday that caused the app to not be able to connect to the DB. We have updated the app now and all seems to work as normal again.
