The Pakistan govenment has been attempting to censor the Internet, in fits and starts over the years. This website is an attempt to catalogue these censorship attempts as they happen.
Pakistan has a long history of censorship, from banning books & magazines to shutting down newspapers and jailing journalists. In the early 2000’s internet usage took off in Pakistan, bringing it to the attention of the government. Sadly, the government has been trying to restrict access to the internet by monitoring and filtering all internet traffic, in the process slowing internet speed for everyone, and violating basic human rights, as specified in the Universal Declaration of Human Rights, which Pakistan is a signatory to.
