Turkey's prime minister made headlines last week by threatening to block Facebook in the country, but as recent events in Nigeria show, a more discreet intervention can be effective in disrupting the free flow of information.
The two websites at the University of Texas at Austin, at first blush, seemed to have been unlikely targets for attack. The Knight Center for Journalism in the Americas and its blog cover news about journalism, press freedom and journalist safety throughout the Western hemisphere, with an emphasis on trends in Latin America. The website of the International Symposium for Online Journalism provides information about meetings and other professional issues. Both websites were shut down for two weeks last month in a targeted cyber-attack.
It's not unusual for Charter 97, a Belarusian pro-opposition news website, to be disrupted online. CPJ has documented intimidations, threats, and arrests against its staff members, the murder of its founder, and denial-of-service attacks against the website.
A founder of Mexican news weekly Ríodoce, Javier Valdez Cárdenas, traveled to New York in November to receive CPJ's International Press Freedom Award at our annual benefit dinner. No sooner had he returned to Mexico than Ríodoce's website was thrown offline by a denial of service (DOS) attack, in which multiple computers are used to flood a webserver with fake requests, slowing down the site so that it cannot serve legitimate requests.
