I'm still facing tons of different exceptions which seems to be GAE issues - as always, GAE status all green. Having these for last three days, I haven't done any deploy and the app was running fine for last >6 months.

Just a note - I'm running some stack on Openshift and Appfog now due to absolute lack of support from the google team here - when I ask for help on their public forums I get a response within tenth of minutes/1-2 hours and the issue is immediately solved.
