The Great Firewall of China

Today is not a unusual day. As as we know that the June Fourth Movement took place 20 years ago, it’s still the dark part of the history that China Communist party never want to mention. Actually for the new generation like me who was too young to know what happened or even didn’t born at that time, we are totally know nothing about that.
OK I don’t want to discuss any topic about politics here. I only want to talk about the “mysterious” Wall.

It is said that Internet can share any information to everyone in the world, but how can it possible to keep our people in main land away from anything about June Fourth Movement.Or what is blocking us from those information that CCP and gov. wanna ban. And that is the Great Firewall of China.
Crossing the Wall (or Bypassing) is a quite popular Internet new word for us. At first, I cross the GFW to fetch the English technology information that I need cause the damn slow connection from mainland to the abroad. But I discover that many sites that I couldn’t connect before can be visited after I use the cross-wall tool. So I am wondering what is building the “Wall” between China and those “sensitive” sites.
As we know, China has the famous Great Wall that was built for defend enemy at the ancient time. And a new type “Great Wall” is built to “defend” the somehow “dangerous” threat in the Internet nowadays.

There is an formal name of GFW actually, the Golden Shield Project. The Golden Shield Project (Chinese: 金盾工程) is a censorship and surveillance project operated by the Ministry of Public Security (MPS) of the People’s Republic of China. The project started in 1998 and began operations in November of 2003. Whatever, we are used to call it the Great Firewall and GFW in short.

The GFW uses many methods for censoring, such as IP blocking,DNS filtering and redirection, URL filtering, Packet filtering, Connection reset. That can make the people in main land only get the error message when they want to visit some web sites.

Excluding those political sensitive web sites, there are many famous new web 2.0 sites are blocked . Web 2.0 change the mode of web world. Anybody can post their idea on the web, such as the personal blog, micro blog, SNS sites like facebook and so on. Only because some users post some “sensitive” information at their own page or comments on some posts. That make the whole site to be on  the ban list at GFW database.

So when we want to vist those banned sites, we have to “cross” the GFW. There are also many ways to make it. You can use the proxy host that provide the tunnel, or to use the new P2P technic, such like Tor.

PS: Most of the photos on my blog are on the flickr. So they are GFWed too. 🙁

for providing reference about Golden Shield Project 😎

    I am from China, I love China, but I hate China Communist party.
    Right now, people in China can’t access,,,,etc.
    even is dangerous now, as the CCTV(also called CCAV by most of the Chinese who has their own mind)reported that Google is spreading some political, pornographic content…..
    what a BIG joke!
