Hi Frank, We've posted a postmortem for the recent issues here: http://groups.google.com/group/google-appengine/browse_thread/thread/e9237fc7b0aa7df5#
On the rare occasions our underlying storage infrastructure has problems, this can cause user-visible outages. In cases like this, we could fail over nearly immediately to another datacenter, but doing so could cause recent datastore writes to be lost. We generally judge a longer outage to be a lesser evil than datastore rollbacks, since people rely on that not happening. We're actively working on mitigating this so we can fail over safely and immediately without risking any loss of data. -Nick Johnson On Thu, Jul 2, 2009 at 9:24 PM, Frank<[email protected]> wrote: > > Dear Google AppEngine Engineers, > > I would like to, respectfully, suggest something to you: drop > everything you're doing and fix this. > > Something is wrong, badly wrong.
