Kremvax

Kremvax was originally a fictitious Usenet site at the Kremlin, named like the then large number of Usenet VAXen with names of the form foovax. Kremvax was announced on April 1, 1984 in a posting ostensibly originated there by Soviet leader Konstantin Chernenko. The posting was actually forged by Piet Beertema of CWI (in Amsterdam) as an April Fool's joke. Other fictitious sites mentioned in the hoax were moskvax and kgbvax. The actual origin of the email was mcvax, one of the first European sites on the internet.
