Operation Egypt was participation by internet hacktivist group Anonymous during the 2011 Egyptian revolution on an attempt to bring the Egyptians freedom of speech.

Background
Anonymous had just completed their very successful Operation Tunisia in which the group provided Tunisians the tools needed to oust their leader, as well as attacking government websites.

The Attacks
In their usual manner, Anonymous posted a video to YouTube declaring their intentions before beginning their operations. Unlike in Tunisia, Anonymous did not provide the Egyptians with resources to circumvent government censorship but rather only launched DDoS attacks against Egyptian government websites. All top government sites were taken offline by the attacks with relative ease and they remained offline until Hosni Mubarak stepped down.
