Don't forget - some countries (eg the US) have an Internet Killswitch at the ready.
We're already being seeded/conditioned by mainstream media that "China's" alleged hacking is a growing concern.
I can imagine a scenario in the not too distant future where an alleged electronic threat is in progress (and Iraq has WMD!) and the Internet Killswitch is put into effect.
(include in that the possibility of mass social unrest and the need to clobber Twitter and FB via the killswitch as has been done by some governments already)
What will happen to all your files and systems on the cloud then?
(some may assert that it wouldn't matter because the internets are down anyway - which I proactively disagree with)
It's not just about YOUR files and infrastructure that you carefully designed for redundancy ("I'm alright Jack") - because there are so many businesses and entities out there that are blindly relying solely upon the cloud...
