Apparently connection from China has been spotty for months, but most in the last 24 hours there have been findings of a “Complete blocking detected.” Hacker News have also noticed that the site is coming up with the same test as BlockedInChina and GreatFirewallOfChina and this seems to indicate that the site has really miffed someone in China. The work around is to use OpenDNS although you do get some packetloss.
