Libya in full internet blackout Libya's internet services have been almost completely shut off, however phone services remain working.

Libya has been completely cut off from any internet communications, according to Renesys internet monitoring company.

Unlike Egypt's internet block, where ISPs stopped advertising their internet protocol addresses to the network which was immediately reflected in internet monitoring results, in Libya, according to Renesys, their analysis of the BGP (Border Gateway Protocol) routing table showed all Libya routes up and stable. It was the traceroutes, which showed no response from Libyan hosts which indicated the country was in a communication black out.

All traffic going to Libya is currently being "blackholed" or disappearing before it enters Libyan netspace.

According to reports, Libyan telecommunications operators are restricting the network bandwidth to halt traffic; this method is similar to when ISPs cut off subscribers for exceeding their monthly limits.

All Libyan hosted government websites tested by Renesys are currently unreachable. Google's transparency report also shows that the company's query traffic from Libya has fallen to zero after queries to YouTube were actually increasing prior to March 4th.

The first shut down of the internet in Libya occurred on February 19th and 20th where Libyan ISPs turned off their servers to prevent anyone from going online.

Google has launched speak-to-tweet in the beleaguered country, this allows people inside Libya to call a phone number and leave a message which will be turned into a tweet.

As with the Egyptian protests, a number of dial-up alternatives to access the internet are being shared across Twitter for Libyans.
