Nerval's Lobster writes "In its second announcement of the kind, Microsoft revealed [Friday] that it received more than 37,000 requests for information on customers of its Skype, Azure and other services from law enforcement agencies around the world. The count does not include requests made using "National Security Letters" issued by the FBI or other U.S. federal agencies that have the force of a warrant or subpoena, albeit without the oversight or control provided by the courts that issue those sorts of orders. During the first six months of 2013, Microsoft received 37,196 requests that covered a total of 66,539 customer accounts. The company refused to provide any information in response to 21 percent of those requests. It provided "non-content data" in response to 77 percent of the requests – non-content data usually includes information such as names or basic subscriber information rather than information on the content of messages or other details describing online activity of those customers. In 2.19 percent of cases, however, Microsoft reports having provided "customer content data" – which includes the content of messages or data stored in accounts owned by Microsoft companies. Ninety-two percent of requests for customer content came from U.S. law-enforcement agencies."
