I like your idea in theory.

But building data centres costs money and a significant amount of it.

I remember when the Warrnambool exchange fire occurred, a discussion was 
had around fire suppression and the lack of it in a critical exchange 
for regional Victoria.

Begs the question did they have appropriate levels of fire suppression 
equipment installed?

No good having multiple lots of equipment if its not being protected 
from fire properly.
