Via BBC News:
As fighting inside the country intensifies, Libya’s links to the net appear to have been completely severed.
Net monitoring and security firms are reporting that no net traffic is entering or leaving Libyan net space.
Renesys said the outage was more than just a “blip” as many sites have been unreachable for more than 12 hours.
Net traffic into and out of the country had been intermittent during recent protests but the cut coincided with a push to oust rebels.
During the early days of the rebellion in Libya, net access was restricted but in early March net traffic started to pick up in areas no longer under the control of Colonel Gaddafi’s government.
Graphs of net activity maintained by Google show a steady rise in traffic to its sites throughout this week. In particular, Libyans were making heavy use of YouTube to post images of the conflict.
