-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 For anyone who follows the NANOG mailing list, this is not news. For those of you who do not, Rich Stiennon pretty much sums it up on his blog: [snip] What could at first have been just one of those days on the Internet where some newbie engineer accidentally announces a spurious route and takes out a segment of the network has turned into an international fiasco. But no, Pakistan has ordered all ISPs to block YouTube. So an ISP in Pakistan decided to announce a route that would re-direct anyone trying to get to YouTube to some other site that probably hosted a warning about the blasphemous content. Results were predictable. YouTube itself disapeared from the Internet, and, I suspect that most of Pakistan is experiencing performance issues as they are receiving ALL of the YouTube requests from around the world. By 2:30 the Internet watch guards had alerted the backbone provider for Pakistan to filter out those malicious route announcements and alerted YouTube to announce more granular routes that would supercede the Pakistani routes, at least in the US. As of this writing, 3:30 Eastern most of the rest of world can still not get to YouTube.
