Youtube down, not OpenDNS
Palo Alto – Online – resolved
posted on February 24, 2008 8:07 pm UTC

Youtube.com is down right now because Pakistan Telecom has decided to (accidentally probably) hijack their IP address space which means that nobody in the world can reach Youtube. This isn’t an OpenDNS issue. Just letting you all know.
This is now fixed. PCCW took far far too long to fix their broken customer (Pakistan Telecom) … Argh.

…what!? I don’t understand… I thought the .com root TLD servers were distributed around the world. I thought IP routing tables were virtually hardwired at the fiber-level to perform intelligent, disaster-circumventing routing.

    From this BBC article http://news.bbc.co.uk/2/hi/technology/7266600.stm

    "Essentially, Pakistan Telecom took over some of the net addresses assigned to YouTube.

    Crucially the path it offered to this group of addresses was faster than the usual one used by the hardware, or routers, that speed traffic around the internet.

    Pakistan Telecom let this address change propagate to the routers of one of its partners - PCCW.

    Routers are constantly in search of faster ways to get the data passing through them to its destination so news about this faster path started propagating across many of the net's routers. "
  • Wow - I wonder if this has anything to do with the recent sabotage on undersea fiber cables. That is, could two Pakistani and Chinese ISPs pull this off - hijack and subvert 67% of Internet traffic to YouTube - if the usual lines were operational?
