But what would you do with the notification? You can't put it in memcache (memcache is usually disabled too) and, trying to put it in the datastore (provided you can do it before it actully goes read-only), will probably be no more efficient than trying a real write anyway.
But that does lead to possibly a quick way to test, try a Memcache set. *"**will instead return False for set() calls ..... In addition, memcache API calls will return immediately during this period, without any additional latency."* 2010/7/6 Viðar Svansson <vidarsv...@gmail.com> > Hi > > It would be nice if AppEngine would post a message to our apps before > it enters maintenance mode and again when it resumes to normal > operation mode.
