You say that the question you intended to ask was "*How is it possible to set up a server that runs less than 24 hours a day?*".  It's not my job to speak for the community, but my gut feeling is that such a question would be on-topic for SF (I definitely have a concrete answer for it, since I do that very thing quite a lot).

To my mind, the problem is that your original question only asks that as a rhetorical flourish ("*How does one even do that?*"), and it asks a *lot* of other stuff that, at least to my mind, is definitely off-topic.  This is because most of it relates to a commercial entity's billing practices and the oddities of Google Cloud's billing calculator ([is not about ...
working with a service provider's management interface][1])

In this specific case, if I were you, I'd delete my original question (before it accumulates any more close votes or downvotes) and ask a new, tightly-focussed one.
