A federal judge in Virginia has ruled that Google is permitted to tell a customer (and only that customer) about two mysterious surveillance orders. The orders were issued in June, 2011 for records (likely including communications content) associated with their Google account. Google is only permitted to notify the subscriber that was the subject of surveillance, should they wish to tell anyone else they wish. The only high-profile federal investigation involving 2703(d) orders is the government’s investigation of individuals associated with Wikileaks. In December 2010, a judge from the same court issued a. court order to Twitter, forcing the company to disclose information about several users.”]
