It may have been connected to the Nashville bombing and the AT&T switching center which was the target of the bomb. That building has a huge SCIF in which NSA has remote monitoring and switching equipment.

Not sure of the page you are speaking of, not enough info. If you use a search engine there is no shortage of web pages with the at&t / nsa contracts, possible nefarious activities, collaborations, locations of the windowless blogs. The only thing I remember reading was that the rv was possibly a white hat to warn people and prevent death. I haven't really looked into it since it happened.
