Wikipedia was blocked in Pakistan on February 4 after authorities censored the website for hosting "blasphemous content" in the latest blow to digital rights in the deeply conservative country. Blasphemy is a sensitive issue in Muslim-majority Pakistan, and social-media giants Facebook and YouTube have previously been banned for publishing content deemed sacrilegious. Pakistan had earlier in the week given Wikipedia a 48 hour ultimatum to remove material, without publicly specifying its exact objections.
