Intervasion of the UK
The Intervasion of the UK was a 1994 electronic civil disobedience and collective action against the 1994 Criminal Justice Bill which sought to outlaw outdoor festivals involving electronic dance music. Launched by a group called The Zippies from San Francisco's 181 Club on Guy Fawkes Day, 5th November 1994, it resulted in government websites going down for at least a week.
