Hi I suggest you do some serious logging in your app so you can see where the time is taken up. If its during initial imports then you may be in a pocket of poor performing appengine infrastructure at the moment. (A few people seem to be having onoing problems since the 27th) In addition it will give you a better insight into how you app is behaving during startup.
It's also possible that you got a DeadLineExceeded during startup that has left you with a broken instance (this can happen if you using things like django). Have a look at the system log and see if all the 500's are due to DeadLineExceeded or just the first one followed by ImportError's or even AttributeError in seemingly odd places. Mind you all of this only applies if your using python. (I have no idea haw the java platforms behave) Rgds Tim On Oct 30, 7:28 am, Bart Thate <[email protected]> wrote: > So i was programming the whole day and night to give my website a new look, > finally got something working and tweeted the website url > -http://jsonbot.appspot.com.
