I just came across this article talking about a secret government surveillance program called Data Analytical Services (DAS). Which could explain we have this on our analytics. Here is some more information about it.
The sketchy surveillance system allows "federal, state, local and Tribal law enforcement agencies to request searches of trillions of U.S. phone records, usually without warrants." The letter was first reported by WIRED, which also analyzed a White House memo revealing details of the Data Analytical Services (DAS) program, formerly known as the Hemisphere Project.
The White House reportedly injected $6 million into the program, but in secrecy, despite the fact that the program was not a "classified project" from a national security perspective. However, according to Senator Wyden, all records of the surveillance program were put behind the "Law Enforcement Sensitive" protection to ensure that they never make it to public knowledge.
Hope this helps
