C-Day
From Tardis Wiki, the free Doctor Who reference
C-Day or Computer Day was set to be the day that all of the world's computers would be networked together and placed under the control of WOTAN. Initially scheduled for Monday, July 16th 1966, C-Day was canceled when the WOTAN computer was destroyed after attempting to take over London. (DW: The War Machines, MA: Who Killed Kennedy)
