Microsoft's new data center strategy could be:

"RAIN":
Redundant
Array of
Independent
Nations

With the proper encoding (e.g., "erasure" coding, etc.)
techniques, Microsoft could engineer a system in which
the data doesn't "live" *anywhere* at all:

With d data centers in c *independent* countries and an
integer m, 5<m<c<d, Microsoft (or any other organization--
Cryptome, Tor, etc., are you listening ??) could arrange
the stored bits so that it would take at least m countries
all *colluding* to be able to read or write any portion of
any individual's data.

I picked the number "5" at random (e.g., 5-eyes).  ;-)
