This is a defining moment in Iran’s modern history; the people of Iran face questions concerning authority in both leadership and in information. Here’s the latest news on some actions taken by the Iranian government to force a cessation to the dispersion of critical communications.

Iran’s government in recent days has tried to cut off Internet access for most of its election protestors by shutting down routers at the nation’s perimeters, ripping satellite dishes off roofs, cutting cables and turning off telephone switching networks.

Iran, in effect, has declared cyberwar on itself. And it doesn’t appear to be winning the fight because of the resilience of a communications grid originally designed to be both resilient and pervasive. In fact, its actions may also be crippling banking systems and hindering commerce in what is a technologically advanced nation. Cutting off Internet access affects more than Web sites or Twitter and Facebook. Credit card and ATM systems could be affected, as could critical infrastructures.
