Wow. Yet another reason why I think governments will attempt to squash it, DNS is the only way to even marginally effectively shut down a site right now.

  Has route blackholing been tried yet? It seems like it would be pretty effective.

    Yes, it has been tried. But it is impractical, because of collateral damage: - Many sites are hosted on massively shared hosts. Blocking those IPs will cause a lot of services to be unreachable, not just the one to be blocked. - People find you with your domain name, not your IP, so a service could avoid filtering by switching subnets every day and just keep updating the DNS entry. After a certain time, the govt will be blackholing a large part of the internet.

    It is. Remember when Pakistan blocked half the world from being able to access Youtube in 2008?[1] (Though that was more incompetence by network engineers than legitimacy of the method) [1] http://www.ripe.net/internet-coordination/news/industry-developments/youtube-hijacking-a-ripe-ncc-ris-case-study http://www.ripe.net/internet-coordination/news/industry-deve...
