Site unreachable several times over 8 days.
Anonymous (group of _chan (many), Ebaumsworld, Something Awful, Encyclopedia Dramatica, Partyvan, etc. users)
TYPE OF ATTACK:
Average attack size of 15000 packets/second (5).
The attack - known as Project Chanology (3) - was at least partically in response to the Church of Scientology's "act of censorship" in getting a video of Tom Cruise posted by Anonymous removed from YouTube (1). The denial of service attacks were just one part of this assault on the Church, which included real-life protests, prank calls, black faxes, and a range of media condemnations. At some point during the attack, at least the primary website was migrated to Prolexic Technologies (5), a host specializing in DDoS.
