We have an old "quiet part out loud" corporate story. It's about how one arm of Google using our service and wondering why it had so much downtime, only for us to point at their GAE arm and say "when they're down, we're down". They went and talked to GAE and - funny enough - were able to correlate the downtime they observed with GAE downtime.
GAE uptime improved, for a little while. Yeah, we're on AWS now too.
