Who makes the servers?
Whre do the components come from?
Where are they manufactured?
Who writes the software?
Where is it installed?
Where does the AC Power come from?
Who does the maintenance?...........................
To me the key one is who owns the AC? Wonder how long AWS would function without power. I’m guessing an AWS server farm uses as much power as a medium sized city. How secure is it? It would be terrible if the provider deciding they didn’t like censorship and deplatforming and cut the cord. Just saying.
Point taken, but the one you didn’t ask which is most important is - who provides the bandwidth? And that may likely have to be some non-US entity. Which in turn means they US can block it
But note that I didn’t make any reference to the internet, you did that. The bandwidth precludes video and large graphics but digital HF radio is an option, but direct broadcast satellites (i.e. cubesats) have been built by high school classes and a number of non-US launch options exist.
And Starlink. It is not priced competitively now for a reason, but after Musk’s vision of 12,000 LEOs is a reality, that will change. It’s usability depends on how sane or crazy Elon Musk is.
