~ How internet works ~

For a few hours in February 2008, Pakistan held hostage all the world’s cute cat videos.
The situation came about when the Pakistani government, in an attempt to prevent its own citizens from accessing what it decided was offensive content, ordered Pakistan Telecom to block access to the video-sharing website YouTube. To do so, Pakistan Telecom falsely informed its customers’ computers that the most direct route to YouTube was through Pakistan Telecom and then prevented Pakistani users from reaching the genuine YouTube site. Unfortunately, the company’s network shared this false claim of identity beyond its own network, and the false news of the most direct way to YouTube spread across the Internet’s underlying mechanisms. Soon over two-thirds of all the world’s Internet users were being misdirected to the fake YouTube location, which, in turn, overwhelmed Pakistan Telecom’s own network.

Gone through the source. Very informative even though it's a basic thing.
