I have tried reaching al the http://codex.wordpress.... links from both Shanghai and Beijing in the last month and none are accessible. The rest of the website is fine, but not the codex links.
Now, I know that many of you outside of China are going to say "It's China's fault for blocking", but I really really doubt this and think instead it's just a DNS issue somewhere either on the WordPress side or somewhere between WordPress and China.
I was hoping maybe WP can provide an alternative URL to access the codex area. I am currently using a very slow proxy to access it...
