Sorry to hear it
Many websites, especially government ones and those like the FAS, are reviewing their content in light of security concerns. I didn't see anything on Kim's website that seemed wrong. Over reactions will be probable for some time to come, such as NASA keeping the next Shuttle launch time secret until 24 hours before launch. As Raoul pointed out, it wouldn't be all that difficult to calculate the probable launch time given the tightness of the window for ISS missions.
