I find the data escrow concept an interesting development:
Microsoft officials previously said that they will be operating in the second half of 2016 two new German datacenters, located in Magdeburg and Frankfurt. These datacenters, which will offer users Azure, Office 365 and Dynamics CRM Online, will offer users the option to have their data-access controlled by a trusted third party, not Microsoft. Officials said that access to customer data stored in these new datacenters would be under the control of T-Systems, a Deutsche Telekom subsidiary, that would act as a data trustee.
