So, I'm sure you're wondering -- just what is Shub-Internet, anyway? Well, the Online Jargon File 4.0.0 file has this to say about Shub-Internet:
[MUD: from H. P. Lovecraft's evil fictional deity Shub-Niggurath, the Black Goat with a Thousand Young] The harsh personification of the Internet, Beast of a Thousand Processes, Eater of Characters, Avatar of Line Noise, and Imp of Call Waiting; the hideous multi-tendriled entity formed of all the manifold connections of the net. A sect of MUDders worships Shub-Internet, sacrificing objects and praying for good connections. To no avail -- its purpose is malign and evil, and is the cause of all network slowdown. Often heard as in "Freela casts a tac nuke at Shub-Internet for slowing her down." (A forged response often follows along the lines of: "Shub-Internet gulps down the tac nuke and burps happily.") Also cursed by users of the Web, FTP and TELNET when the system slows down. The dread name of Shub-Internet is seldom spoken aloud, as it is said that repeating it three times will cause the being to wake, deep within its lair beneath the Pentagon.
[January 1996: It develops that one of the computer administrators in the basement of the Pentagon read this entry and fell over laughing. As a result, you too can now poke Shub-Internet by pinging shub-internet.ims.disa.mil. See also kremvax. -- ESR]
In case you're wondering, yes I was that administrator. The thought has remained with me ever since. When casting about for a personal domain to have registered (but which hadn't already been taken), this became self-evident.
So, there you have it, and welcome to the web pages of Shub-Internet.
