"The numbers reported above include all types of government data requests such as criminal law enforcement requests and those under U.S. national security authorities, including the Foreign Intelligence Surveillance Act (FISA) and National Security Letters (NSLs), if any were received.<p>The U.S. Government does not permit us to disclose additional details regarding the number of requests, if any, under national security authorities at this time, or even to separate them in aggregate from other requests. Additionally, the government would not authorize us to separate NSLs from other government data requests or to express the NSLs that we have received, if any, as a range from 0 to 1,000—even though the government allowed other providers to do so in the past. We strenuously disagree with the government's position and will continue to advocate for greater transparency regarding requests made under national security authorities. If we succeed in persuading the U.S. Government to allow greater transparency, we will disclose additional details in future reports, and we will also update this report with more details related to national security requests as permitted."<p><i>Range from 0 to 1,000</i> a hint?
