Thank you for your reply. The log tells that it is the initialization of a new instance that takes longer than 60 seconds and therefore it is shut down. This means that no new instances could be started causing our service to be completely down.
The strange and unanswered part is still that our source code had been running for a couple of months without any change. Then this problem happened for 12 hours and suddenly it worked again. For the past 3 days everything has been working, but we still did not change the code. Not before, not during the down period and not after the down period. That leads me to think that Google is using us as beta testers for internal changes.
