He chose to release it into the Internet from MIT, to disguise the fact that the worm came from Cornell. Morris soon discovered that the program was replicating and re-infecting machines at a much faster rate than he had expected. Finally, many machines at locations around the country crashed. When Morris realized what was happening, he contacted a friend at Harvard to discuss a solution. Eventually, they sent an anonymous message from Harvard over the network, instructing programmers how to kill the worm and prevent re-infection.
