The video-sharing website YouTube says it was taken out of service on Sunday after Pakistan's government ordered the site to be blocked because it contained un-Islamic material. Should governments censor internet sites?
The owner of YouTube, Google, says the nearly two-hour outage of the website was caused by what it calls "erroneous internet protocols", sourced in Pakistan.
The Pakistani authorities ordered the Islamic republic's internet service providers to block the website because its content included Danish cartoons depicting the Prophet Muhammad.
Pakistan Telecom Authority "hijacked" the web server address of YouTube and the video web site was mistakenly blocked by internet service providers around the world.
In what circumstances would you allow governments to block access to the internet? Do you believe any censorship is an attack on freedom of expression?
