Most of the world's Internet users lost access to popular video sharing site - YouTube for several hours on Sunday, after an attempt by Pakistan's government to block access domestically affected other countries.
On Friday, the Pakistan Telecommunication Authority had ordered 70 Internet service providers to block access to YouTube.com because of anti-Islamic movies on the video-sharing site. The block was intended to cover only Pakistan, but it extended to about two-thirds of the global Internet population, starting at 1:47 p.m. EST Sunday.
This outage highlighted yet another of the Internet's vulnerabilities, coming less than a month after broken fiber-optic cables in the Mediterranean took Egypt off line and caused communications problems from the Middle East to India. An Internet expert said Sunday's problems came after a Pakistani telecommunications company complied with the block by directing requests for YouTube videos to a "black hole." Link
