The series of tubes famously dubbed the ‘internets’ by President
G.W. Bush constitute a world wide web of interconnectedness. But, as this map
demonstrates, there are some black holes in that web. They represent the 15 countries that limit or prohibit
their citizens’ access to internet as a way of censoring the free flow of
information.

Perhaps most notorious among those countries is China, with its Great Firewall (and its
insistence on self-censorship by non-Chinese companies operating within the
Middle Kingdom). Other countries also maintain firewalls, notably Saudi Arabia, while less-developed
nations might just not allow their citizens to own computers.

This map was commissioned by “Reporters Without Borders”,
which also publishes a World Ranking of press freedom. As the list of the 15
internet-restricting countries (followed by their ranking on said list)
indicates, internet censorship is a strong indicator of press censorship in
general:

1. Maldives (144)

2. Tunisia (148)

3. Belarus (151)

4. Libya (152)

5. Syria (153)

6. Vietnam (155)

7. Uzbekistan (158)

8. Nepal (159)

9. Saudi Arabia (161)

10. Iran (162)

11. China (163)

12. Myanmar/Burma (164)

13. Cuba (165)

14. Turkmenistan (167)

15. North Korea (168 and very last on the list)
