A blog post by Renesys Corporation experts, who provide network data collection and analysis services, suggests that access to all but one of Iran’s five major international data connections has been severely degraded. Some have speculated that this is because the Government of Iran, which controls most national telecommunications systems, has imposed a strict regime of Internet filtering on its population.
Notwithstanding these events, activists organised their protest efforts through online messaging sites such as Twitter, which had apparently been overlooked by censors. One message implored activists to climb to the rooftops and give voice to their protest by shouting ‘Allah’u akhbar’ (God is great). By 4:00 a.m. local time on June 13th, the noise of the rooftop protest was deafening. The outcry has only increased since then. Significantly, the same tactic was used at the outset of the 1979 revolution that ousted the US-supported Shah of Iran and ultimately led to the rise to power of the current theocratic regime.
This riveting spectacle provides us with an object lesson in the effects of communications networks on democracy and social movements.
