A new web technology being championed by China is allowing a short-term gap in its so-called “Great Firewall,” which blocks Chinese Internet users from sites blacklisted by the government in Beijing. Experts say how the gap is closed could have ramifications for the entire world.
The gap exists because of IPv6, the next generation of Internet protocol designed to replace IPv4. The change is needed because the old system is about to run out of IP addresses, the combination of numbers that identify your computer over the Internet. IPv6 will offer a nearly infinite number of IP addresses.

Seems that there's a flaw in the slaw in China's Great Firewall, as it may not be able to handle IPv6, which will provide infinite numbers of IP addresses. Those who claimed to use IPv6 to get around China's censorship firewall were successful, such as users inside or outside China.
