The Intervasion of the UK was a 1994 electronic civil disobedience and collective action against John Major's Criminal Justice Bill which sought to outlaw outdoor dance festivals and "music with a repetitive beat". Launched by a group called The Zippies from San Francisco's on Guy Fawkes Day, November 5, 1994, it resulted in government websites going down for at least a week. It utilised a form of Distributed Denial of Service (DDoS) known as the Email bomb in order to overload servers as a form of and Internet activism. It was the first such use of the Internet and technology as a weapon of struggle and/or civil disobedience, and preceded the 1995 Italian NetStrike.
