The DEFCAD site shows the following:
DEFCAD files are being removed from public access at the request of the US Department of Defense Trade Controls.
Until further notice, the United States government claims control of the information.
We do not know if this is real or not. There was a similar spoof done on April 1st.
We will learn more in the next few hours. This may be real.
