Effective Measure CEO Scott Julian has confirmed to TechCrunch that Internet access in Libya is indeed restricted, but not totally cut off. Effective Measure measures analytics tags on pages like arabia.msn.com within the MENA region.
“At around 10pm local time, Internet traffic dramatically dropped across the board. Whilst not completely cut off it’s clear it’s a pretty concentrated effort, which in my opinion is unlikely to be the result of a random failure.”
“The profile of the change in traffic is very similar to what we saw in Egypt, and leads one to conclude that this isn’t the result of a group of random, unconnected events. It seems some ISP’s are still up and running, which follows the same pattern as the first shutdown in Egypt.”
Twitter user Ramy Raoof says that sources in Libya have cited the Facebook blocks, but that Twitter.com is still not blocked and Internet access is not yet down. I have contacted both companies for information and will update this post as soon as they respond.
