As a reader and future writer in China, I always have trouble connecting to Lush without technological assistance. It seemed that the Chinese government have put the IPv4 address of Lush onto the blacklist of a national firewall together with Facebook.
However there are two things that can be used: 1) unlike Facebook, Lush is not blocked in the DNS system, which mean that our Chinese readers can still get the correct address, but the connection is jammed, and 2) there is no evident that the national firewall can do anything about the IPv6 protocol, even if it is tunneled in IPv4 packets that does not enforce encryption.
Based on this, if Lush start to provide IPv6 access, it will be easier for us Chinese readers to connect to Lush, if the IPv6 can be connected or tunneled properly.
