Another issue we're running into now (as a result of having a growing number of users) is that we're noticing that downtime on the App Engine is shockingly bad, and getting worse. Over the last few weeks, we've seen periods of downtime pretty much daily, and serious downtime (i.e. more than a few minutes) monthly. It's grossly under-reported in the App Engine status console, which shows a euphemistic warning (which in practice might mean that all server requests will return errors.) Our software is used in the classroom during lectures, and we've had several customers experience system failure due to App Engine downtime. On top of that we've had more than one customer demo go wrong for the same reason. It's pretty infuriating actually, because 1. you can't do anything other than just sit there and wait it out, and 2. there is no one to talk to at Google. Finally, the problems are only getting worse. We were going to do a slow migration out of the App Engine over the course of a few months (because we've got a ton of code to rewrite.) At this point we're doing an emergency 2 week migration with all devs pulled from their projects for the task. I honestly have no idea why these issues aren't getting more mainstream attention, given how many people are using the App Engine. The only thing I can come up with is that there must be tons and tons of tiny non-critical projects, and very few serious startups betting their business on the App Engine.
