One of the lessons we were taught in our security briefings was that just because something was publicly discussed somewhere (e.g., on a television show or in the newspaper) does not automatically make the information unclassified.
It works the other way too. I've found things I write in public about Internet outages have a habit of ending up in places you need clearence. Someday it would be nice if I could read what I wrote. Scroll down this page: http://www.ncs.gov/n5_hp/Customer_Service/XAffairs/NewService/2000-063.htm The NCS gets the information the same way as everyone else. They subscribe to NANOG. To bring this on topic: How would ISPs feel about officially contributing to NCS's efforts on tracking Internet outages? Would you be willing to subscribe the NCS to your customer outage notification lists?
I personally know of classified data that has been leaked and published in print, and that's about all I'll say on that particular subject.
Last I heard, the Department of Energy library still considers the February 1979 issue of "The Progressive" magazine classified. You might find it in some public libraries. http://www.law.umkc.edu/faculty/projects/ftrials/conlaw/progressive.html
