Segregation
Will those "Cloud" servers be physically separated from the Internet, not very likely, otherwise they wouldn't be "cloud" in nature. If they are not separated then how are they guaranteeing data privacy from snooping 3 letter agencies on the other side of the pond.
Will their be offsite replicas, if so where. The articles mentions 2 data centres without mentioning their location.
Who is the "data trustee"...
I would like to see if they can manage to get the Swiss to validate everything... The Germans didn't even manage to secure their Chancellors phone....
And because this is Microsoft, whose laws applies when the SHTF, American or European.
Will the Brits be allowed to use the new EuroCloud, if so, and because of their very friendly nature with the Americans, this could lead to some serious doubts....
