A US court has upheld an earlier ruling requiring Microsoft to hand over data held in its data centre in Ireland to the US government. The US government had obtained a search warrant requiring Microsoft to hand over certain data, including emails, stored at its premises. This latest ruling has confirmed that Microsoft is not only required to hand over data stored on US servers, but all relevant data regardless of its location. Microsoft has confirmed that it will appeal against the extra-territorial effect of the warrant on the basis that “people’s email deserves strong privacy protection in the US and around the world”.
