From The Washington Post:
If you happened to be searching for a video at YouTube.com Sunday afternoon, there’s a good chance your browser told you it was unable to locate the entire Web site. Turns out, much of the world was blocked from getting to YouTube for part of the weekend due to a censorship order passed by the government of Pakistan, which was apparently upset that YouTube refused to remove digital images many consider blasphemous to Islam.
According to wire reports, Pakistan ordered all in-country Internet service providers (ISPs) to block access to YouTube.com, complaining that the site contained controversial sketches of the Prophet Mohammed which were republished by Danish newspapers earlier this month. The people running the country’s ISPs obliged, but evidently someone at Pakistan Telecom – the primary upstream provider for most of the ISPs in Pakistan – forgot to flip the switch that prevented those blocking instructions from propagating out to the rest of the Internet.
