中国于2002年开始使用DNS劫持技术封锁网站。动态网络技术公司（DIT）于2002年10月2日发布一份报告演示这种技术如何运作。这些年来，我们对于中国如何使用这种DNS劫持技术有了更多的了解。2014年1月21日，中国由于DNS劫持发生大规模网站断网。我们觉得现在是发布关于这个系统的更多信息的好时候。
In 2002, China started to use DNS hijacking technology to block web sites. Dynamic Internet Technology (DIT) released a report on October 2, 2002, to demonstrate how it works. We gain more insight into how China is using this technology throughout the years. On January 21, 2014, there was a large-scale Internet breakdown in China caused by this DNS hijacking system. It is a good time to release some of the additional information we have about the system.
China, with a population of over 1.3 billion, is the world's largest Internet market. Nearly half of China's population are Internet users. By the end of 2012, registered users of Sina Weibo had already surpassed 500 million. 46 million of these are very active users. These staggering figures can often lead to a misunderstanding that China's Internet is as free as the Internet overseas.
