Pakistan blocks YouTube, ends up getting blocked from the internet.

In Pursuit of "Happyness"
4:30 PM Eastern (US).
The telecom company that carries most of Pakistan’s traffic, PCCW, has found it necessary to shut Pakistan off from the Internet while they filter out the malicious routes that a Pakistani ISP, PieNet, announced earlier today. Evidently PieNet took this step to enforce a decree from the Pakistani government that ISP’s must block access to YouTube because it was a source of blasphemous content.
I cannot let the irony pass with out commenting. A religious state, Pakistan, identifies a content provider, YouTube, as the source of blasphemous, seditious content and orders, King Canute style, that the Internet tides be stopped. A zealous ISP ignorantly decides the best way to comply with the decree is to re-route all of YouTube’s IP addresses to whatever site they thought was more appropriate. The first repercussion was that YouTube disappeared from the Internet for almost an hour. I suspect the second repercussion was that Pakistan’s Internet access crawled to a halt as all of a sudden they were handling IP requests for one of the busiest sites in the world. As of this writing YouTube has announced more granular routes so that at least in the US they supercede the routes announced by PieNet. The rest of the world is still struggling. So, while working on a fix that will filter out the spurious route announcements, PCCW has found it necessary to shut down Pakistan’s Internet access. The leadership of Pakistan just created a massive Denial of Service on their own country.
I could say: “be careful what you wish for” to those elements that object to free and open access to information and expression of ideas. But to put it in terms they might understand better: Do not anger the Internet gods or you will suffer their wrath!

Must have routed it to Yahoo or something. They are the busiest sites in the world. But I still do not understand, how could it have taken down entire connectivity.

It looks like they took the entore routing of Youtube upon themselves or atleast a major part of it. Its all a big mess.

Pakistan wanted to show a "Not Available" or "Blocked" page whenever someone tried to access YouTube from Pakistan. For this, they wanted to re-route all traffic going to YouTube so that it may reach their own "Not Available" page. All this re-routing is done by inserting/deleting/modifying rules in a routing table. The only mistake they did was that they placed their rules over and above YouTube's own GLOBAL rules! Hence they entire global traffic of YouTube was diverted to pakistan's "Not Available" page :p

^^ Cause they corrupted the Internet's routing table! All high priority rules are propagated to all the other routers, and they adjust their routing tables accordingly..
