If you are familiar with China and their internet, you know that China filters their country's internet access using what is known as the Great Firewall in order to keep their population from seeing web pages that run counter to the wishes of China's government. Internet users in mainland China are forbidden from accessing many popular western websites, such as Facebook, Twitter and Gmail.
When a user in China tries to access a blocked website, the Great Firewall will send the user's request off somewhere else. China will funnel requests for a blocked site off to a different IP address unrelated to the blocked site. It appears that China's firewall chooses these IP addresses at random. This can cause issues when there is a valid website running at the IP address China sends these blocked requests to.
