From the source of all knowledge

On February 22, 2008, Pakistan Telecommunications Authority (PTA) attempted to block regional access to YouTube following a government order. The attempt inadvertently caused a worldwide YouTube blackout that took 2 hours to correct.

Sadly the reference link is broken. How can a websites with presumably servers around the world be accidentally taken out? I'm interested in the technical details of what the authorities did that disabled YouTube.

I remember that event!

The European IP Network's Network Coordination Centre (RIPE NCC - the acronym makes more sense in French) issued a case-study about the incident.

On Sunday, 24 February 2008, Pakistan Telecom (AS17557) started an unauthorised announcement of the prefix One of Pakistan Telecom's upstream providers, PCCW Global (AS3491) forwarded this announcement to the rest of the Internet, which resulted in the hijacking of YouTube traffic on a global scale.

It contains the technical details on the IP range hijacking.
