Yes, that was the decision three years ago -- but we're going to do things slightly differently going forward.
StackOverflow (SO) is about **software development** questions, with some further constraints -- see
http://stackoverflow.com/help/on-topic . The SO community understandably does *not* appreciate questions that are not about SW development -- in particular, questions about system and network administration have their own site within the same "stackexchange" family -- ServerFault (SF).
Many technical questions about App Engine are indeed about SW development and perfectly appropriate for SO -- great!
*But* a few technical questions are instead about system and network administration -- and, for those, SF is the right place.
And of course some questions are not welcome on either site -- for example, quoting from the FAQ above, "Questions asking us to recommend or find a book, tool, software library, tutorial" are not welcome there. For those kind of questions, this Google Group is therefore the best place to ask!
I would consider this specific question to be most likely a system administration one -- thus more appropriate for Server Fault (with the same tag). We do sponsor and monitor tags "google-app-engine", "google-compute-engine", and "google-cloud-platform" on both SO and SF. Yes, I do need to change
https://cloud.google.com/support/ , which does not mention ServerFault; I'm working on that:-).
To me, it's part of acknowledging that we don't only have a *developer* community -- there's also a community of *system administrators*, some of whom may also be developers, but not necessarily all of them -- likely a smaller community, but highly professional and fully deserving of our support and recognition. (The issue looms larger for other Google Cloud Platform products, like Google Compute Engine, where the ratio of developer vs sysadm questions is also larger than for App Engine; but it makes sense for GAE, too!-).
...and happy system-administering, too!-)
