Hi Tim, I presume GAE requests can come from a large number of different IP's. My app has been working fine for months, but then I made a small change, did an upload and it suddenly stopped working with this error, so I can only assume my app started coming from a different IP due to that upload, and the new IP had already made a lot of Twitter requests. Can the apps spontaneously change IP? I don't know enough about Google's infrastructure to diagnose. It could be that your app will be blocked the next time you upload it, that's what happened to me. Good luck with your upload roulette :-)
