Something has gone really wrong with app engine. Here's my post: http://groups.google.com/group/google-appengine/browse_thread/thread/5373a2efe1a973bb
I would also suggest that people star this issue relating to giving us an sla, at least for paid accounts: http://code.google.com/p/googleappengine/issues/detail?id=501 Lastly I would suggest to google that if they are not aware of this issue then their monitoring tools need to be improved. They need to know the overall 500 error rate for appengine applications. If they do, then they could easily see that this has spiked recently. There will always be a certain background level of 500 errors but a sudden increase needs be proactively investigated. I know that google is looking into this, but at what level I don't know. I'm thinking it might be related to this issue, loading of an instance takes too long: http://code.google.com/p/googleappengine/issues/detail?id=1695 that's pure speculation on my part. It might be that a single server or cluster of servers are acting up and when a request goes to that group we see the problem.
