[google-appengine] Re: App Engine geographic distribution
Hi, GAE datacenters are not yet distributed, but will be (or are already with hardware maintenance that took place a week ago) as time goes on. Bear in mind that to commit transaction you'll need extra 50ms to ensure that transaction is committed in all datacenters serving GAE apps worldwide. Regards, m.

[google-appengine] Re: App Engine geographic distribution
I can't comment as to the precise geographic distribution of apps and appservers, but let me put it this way... (a) our datastore API offers transactions (b) a datastore transaction completes in roughly 50ms, sometimes less (c) when routing requests to applications we have no idea which entity groups will be modified by the application when serving that request. further, we don't ask for any hint or indication of this from the application developer.

I did search. A bump is appropriate for this topic because Google simply hasn't seen it yet. It is a simple yes or no answer and when Google or someone who knows sees it, it will be solved and searchable for future GAE users.
