On April 1, 1984 Piet Beertema posted that the Soviet Union was going to join Usenet.  The post was to have come from Soviet leader Konstantin Chernenko.  The Kremlin Usenet site was to be named Kremvax.  Year’s later Vadim Antonov had a subdomain placed on the first legitimate Soviet Usenet site – kremvax.demos.su showing that the April Fools’ Day prank had a lasting impact.

Here is the original post in the eunet.politics newsgroup.  Archived in Google Groups.

Well, today, 840401, this is at last the Socialist Union of Soviet
Republics joining the Usenet network and saying hallo to everybody.

One reason for us to join this network has been to have a means of having an open discussion forum with the American and European people and making clear to them our strong efforts towards attaining peaceful coexistence between the people of the Soviet Union and those of the United States and Europe.

We have been informed that on this network many people have given strong anti-Russian opinions, but we believe they have been misguided by their leaders, especially the American administration, who is seeking for war and domination of the world.

By well informing those people from our side we hope to have a possibility
to make clear to them our intentions and ideas.

Some of those in the Western world, who believe in the truth of what we
say have made possible our entry on this network; to them we are very grateful. We hereby invite you to freely give your comments and opinions.

Here are the data for our backbone site:

Name: moskvax
Organization: Moscow Institute for International Affairs
Contact: K. Chernenko
Phone: +7 095 840401
Postal-Address: Moscow, Soviet Union
Electronic-Address: mcvax!moskvax!kremvax!chernenko

And now, let’s open a flask of Vodka and have a drink on our entry on
this network. So:

NA ZDAROVJE!
