Great Chinese LAN

The filtered, monitored version of the internet available in China.

A local area network (LAN) is a computer network covering a small geographic area, like a home, office, or university campus. Computers in the LAN can share files and other information, as well as a connection out to the internet. A network administrator oversees activity.

Similarly, the internet in China operates in many ways separately from the rest of the world, with internal content and access to the wider global internet carefully managed. Major services like Twitter, Facebook, and Google are blocked, while home-grown services such as Weibo, Renren, and Baidu take their place. These Chinese web services monitor, filter, and censor content at the behest of the Chinese government.

Example:

Leidigagaxiaohaha (@雷帝gaga笑哈哈): When Google was blocked the idiots said we have Baidu, and Google has “wheels”* and should be blocked. Then when Google Scholar, Dropbox, and Gmail were blocked—tools which the global scientific community depend on—the idiots told us to spend a little on a VPN and quit whining. Now all the VPNs are dead, but don’t worry, the idiots always have something to say. In the future, the Great Chinese LAN will be more restricted than you can imagine, and the pile of censored content will only grow, because the Party takes care of everything that doesn’t obey its rules.

以前google被封时傻逼们说有百度，google有轮子，该封；后来google学术dropbox和gmail这些和世界科研生产力密切相关的都被封了，傻逼们说花点钱用vpn别抱怨；现在vpn全死了，但放心，傻逼们永远有话说。大中华局域网未来一定比能想像的更封闭，禁掉的消失的一定会越来越多，因为党专治各种不服。 [Chinese]
