Comments on: China Re-Blocks Sites Open During Olympics http://blogs.law.harvard.edu/idblog/2008/12/17/china-re-blocks-sites-open-during-olympics/ Thoughts from the Internet and Democracy Project team at the Berkman Center for Internet and Society Sat, 28 Nov 2009 10:33:58 -0500 http://wordpress.org/?v=2.8.5.2 hourly 1 By: Queen http://blogs.law.harvard.edu/idblog/2008/12/17/china-re-blocks-sites-open-during-olympics/comment-page-1/#comment-20290 Queen Sat, 07 Nov 2009 11:00:26 +0000 http://blogs.law.harvard.edu/idblog/?p=333#comment-20290 I discovered recently Skydur.com - a little proxy, unfortunatelly not free. I wish it is free but it's not so expensive neither - just about $5 bucks per month. I can now access all web sites again from China - youtube, twitter, facebook and hulu. Skydur is very fast and works on Windows, Mac and Linux - check it out here - http://www.skydur.com - you won't be disappointed. Believe me I tried dozens of free proxy programs and noone worked as advertised. I discovered recently Skydur.com – a little proxy, unfortunatelly not free.

For instance, suppose I ask you to calculate the shortest route for a person to take on a multi-city trip, adding another city to the trip (to the question) takes N time, solving the new problem will increase by N^x time. This was a very roundabout way to get to my query: does content on the internet increase at a rate that is insoluble to the Great Firewall? Does the Firewall do ad hoc scanning of every page, or does it create a central registry of links? I noticed that, when I was living in China, pages like http://en.wikipedia.org/wiki/Tank_Man would load in their entirety--including the iconic picture. But as soon as it had loaded completely the page would disappear and be replaced with a 404 error.
