The first message sent over the internet was a crash

On the night of October 29, 1969, a programmer at UCLA typed two letters to a computer in Menlo Park. Then the system fell over. History recorded what was actually sent.

Charley Kline was twenty-one years old when he sat down at a terminal in a UCLA computer lab at 10:30 p.m. on October 29, 1969. His assignment was to log in remotely to a computer at the Stanford Research Institute in Menlo Park, 350 miles away — the first attempted message across what would become the internet.

He had a phone line open to Bill Duvall at SRI. He typed an L. Duvall confirmed receipt. He typed an O. Confirmed. He typed a G and the system crashed.

The intended message was login. The actual first message transmitted across a computer network was lo.

Leonard Kleinrock, the UCLA professor supervising the experiment, noted afterward that they should have prepared something memorable — the way Samuel Morse had written "What hath God wrought" and Alexander Graham Bell had said "Come here, Watson, I need you." Instead, what the log recorded was an accident, a failure, and inadvertently a kind of poetry.

The crash was fixed within an hour and the full login completed. Kline scribbled notes into a logbook and went home to bed. Duvall stopped for a burger on his way home. Neither described celebrating.

The network that began that night eventually became one of the most consequential structures in human history. It started with two characters and a bug.
