Twitter on iranian elections

Although the Iranian government’s main telecommunications provider had shut off text messaging services and had cut off access to most social networking Web sites by Monday morning, Iranian Tweeters were still able to communicate with the outside world using a continuously shifting series of proxy servers that they were posting periodically on Twitter throughout the day. Additionally, the Tweeters were instructing their followers to use pagereboot.com, a site that automatically refreshes Web addresses every second, to launch distributed DoS attacks on key government Web sites. Iranians also used Twitter to organize nighttime rooftop rallies where demonstrators would climb to the roofs of their buildings and chant slogans protesting the alleged fraudulent election.
