Meanwhile... Gmail etc are working quite fine. So the claim that if you build on GAE you "take advantage of the same infrastructure used for Google services!!" starts to ring a bit hollow.
Or perhaps they are older than the affected infrastructure and just haven't been rewritten. Or perhaps they happen to not use the affected resource.
In fact, affected services include developers.google.com and code.google.com, and to a lesser extent youtube.com.
I know the claim of running Amazon.com on AWS was initially bogus, but did anyone notice trouble on that site with the recent AWS outages? It would be instructive to know how much they have integrated it since.
