How easy is it to cut off a country from the web?

Many parts of Syria have had their internet and mobile phone access cut off.

Syrian activists who oppose the president often use cameraphones and social networking sites to tell people across the world about the violence in the country.

The Syrian government has blamed "terrorists" for the disconnection.

There are reports of heavy fighting between rebels and government troops in the south of capital Damascus.

Monitoring companies said access was cut on Thursday afternoon.

Google reported on Thursday that Syrians couldn't access any of its services, including YouTube.

There are very few foreign journalists in Syria and reporting on the conflict is difficult and dangerous, so it's hard to know everything that's going on.
