New Semi-Censorship

We are currently monitoring more than 12,000 keywords on Sina Weibo, out of which around 2500 are currently blocked. When searching for any of those blocked keywords, you get the following message:

根据相关法律法规和政策，“[the blocked keyword]”搜索结果未予显示。

This translates into:

These keywords generate no search results at all. Recently, however, a new form of self-censorship has emerged in which some results are returned but not all (big thanks to Jason Ng at BlockedOnWeibo for letting us know). Take, for example, weibo: 八九纪念 ("remember 89") and weibo: 河蟹 ("river crab", used instead of 和谐 which means "harmony" and is used to refer to censorship). These had been fully blocked since we started monitoring them in May this year. However, sometime in September, searching for either of the two started returning some results, followed by this new message:

 根据相关法律法规和政策，部分搜索结果未予显示。

which translates into:

According to relevant laws, regulations and policies, some of the search results for [the blocked keyword] can not be displayed.

An even more interesting example is weibo: 民泽江. It used to be fully blocked, but in September was partially unblocked (displaying the message quoted above). Then, at least as of October 1, it has been fully unblocked.

This new semi-censorship level resembles the one practiced by Baidu, which admits to self-censoring but still returns selected results.

We continuosly monitor more than 5000 keywords on Google, of which almost 2000 are currently blocked in China. Usually this number changes with current events. For example, when http://www.bloomberg.com was blocked in June, the keyword google: bloomberg was blocked as well. In March, when there were rumors of a coup, google: 政变 was blocked. And as the Bo Xilai scandal unfolded, you could not search for google: Heywood. However, in the whole month of September, we didn't detect one single new keyword being blocked on Google. One keyword was unblocked (google: 亡国).

It's not as if the authorities didn't have anything to censor - the conflict with Japan as well as the upcoming leadership transition provide plenty of material. And indeed, they are censoring - on Sina Weibo and probably other local websites, but apparently not on Google.

Google vs Sina Weibo

Three seemingly sensitive keywords that were blocked on Sina Weibo during September are:

1. weibo: 克强 (as in 李克强, Li Keqiang, the upcoming premier of China)
2. weibo: 自焚 (self-immolation)
3. weibo: 张培莉 (Zhang Peili, wife of Wen Jiabao, the current premier of China)

However, none of these keywords have been blocked on Google:

1. google: 克强
2. google: 自焚
3. google: 张培莉

At the same time, four sensitive keywords that were unblocked on Sina Weibo in September are:

1. weibo: 薄熙来 (Bo Xilai, the previous mayor of Chongqing and Politburo member who was recently ousted from the Communist Party of China)
2. weibo: 抗议 (protest)
3. weibo: 大使馆 (embassy)
4. weibo: 日领馆 (Japanese Consulate)

Again, on Google, none of the keywords have changed - the first one has stayed blocked, and the other three were never blocked in the first place:

GlobalWebIndex published a new report on Internet usage around the world this week, and it contained some great news for China. Twitter, Facebook and Google+ have increased their user numbers dramatically in China, as seen below. There's just one problem. They are all blocked in China, and we believe that GlobalWebIndex has got its data wrong (as do TheNextWeb):

Many Blocked New York Times Articles

The Chinese edition of the New York Times - http://cn.nytimes.com - is not blocked. However, numerous individual articles are. We are now automatically importing all articles in their China section into our system for testing. You can view them all here. It does not seem that URLs are blocked based on keywords. For example http://cn.nytimes.com/article/china/2012/07/10/c10wang is blocked whereas http://cn.nytimes.com/article/china/2012/08/18/c18wang is not. This suggests that the authorities are manually reviewing each article to decide whether it should be allowed or blocked.

New Blocked Keywords

These keywords were not blocked in China before August 2012. From sometime in August and onwards, they have all been blocked. Many of them are variants of 胡 as in 胡锦涛 (Hu Jintao, the current president of China who is expected to hand over power to his successor this year).

News Sites Update

After Bloomberg was blocked in June, we are tracking whether other news websites will follow with great interest. Of particular interest is http://cn.nytimes.com - the Chinese version of the New York Times which was also launched in June. It has not yet been blocked. The Hong Kong edition of Yahoo! News was less lucky. http://hk.news.yahoo.com was blocked on July 3 and has stayed inaccessible in China since. Yahoo! China (http://cn.yahoo.com), which is hosted in China and operates under Chinese censorship regulations, is still working well though.

Bye-bye Slideshare

http://www.slideshare.net was blocked on July 11 and has stayed blocked since. This is the first time that Slideshare has been permantently blocked since we started monitoring access to it from China in March, 2011.

The big question for people following online censorship in China is a simple: is censorship increasing or decreasing in China? Many cite the growth of microblogs such as Sina Weibo, as well as the total number of Internet users in China, and argue that while censorship is pervasive, overall, things are opening up. However, two developments during the month of June suggest otherwise. The first was that Bloomberg was blocked, the first time in years that a major, English-language news website was blocked. The second was that out of the 15,000+ keywords on Sina Weibo, Google and Wikipedia that we are monitoring, an additional 231 were blocked while only 24 were unblocked. It would seem that the grip on censorship is tightening.

In a curious incident, Henan News published a story mentioning the Great Firewall by name both in Chinese and English. The story was quickly deleted, but thanks to Google Cache you can still view it here.

After analyzing our May data, which now covers more than 30,000 URLs, we can confidently say that the month of May was uneventful. Few major websites were blocked or unblocked. Perhaps this lack of activity was related to leadership change in China (and not just at the very top - see Rumors say China's chief internet censor replaced. While the Great Firewall didn't change much, Google and Sina, in very different ways, both took important steps in trying to deal with the pervasive censorship.

Google Strikes - The Great Firewall Hits Back

"We have observed that searching for certain keywords on Google from within mainland China will often lead to a temporary service disruption." 
Google Support, May 31, 2012.

Starting on May 31, Google displayed a warning message to users from China if they enter any of the many keywords blocked by the Great Firewall. Users could choose to continue the search which would most likely result in the connection being reset for a minute or so. Or they had the possibility to edit the search query and find another, non-blocked, way of searching for the same thing.

We were excited yesterday to see Google roll out a new feature that warns users trying to search for keywords that would otherwise be blocked by the Great Firewall. It seems that the feature has now already been disabled by the GFW blocking access to the javascript file which does the magic. More on that in our soon-to-be-published monthly newsletter. Meanwhile, we couldn't resist reverse-engineering the list of blocked keywords that Google used. Neither could the team at http://www.atgfw.org who beat us to it. Anyway, better late than never, here is the full list. We will be importing all of them into our system shortly for automatic and continuous testing.

Good news, everybody. We've worked out a simpler solution to unblock websites in China. Visit unblock.cn.com for more detail

This is a step by step guide on how to unblock your website for visitors in China without them having to do anything. The Great FireWall of China is a complicated filtering system capable of blocking websites by a variety of methods. The common methods used are IP blocking, URL and Packet filtering by connection reset, TLS (SSL) certificate filtering by connection reset and DNS hijacking.

IP blocking

Use CDN (Count Delivery Network) to hide the real IP of your site from GFW. I did a simple test myself. I created a Google site and linked it with 4 subdomains as follows.

CNAME records: (ghs.google.com is currently not blocked in China)

test1.example.com -> ghs.google.com   CDN enabled

test2.example.com -> ghs.google.com

A records: (216.239.32.21 is subject to IP blocking in China)

test3.example.com-> 216.239.32.21  CDN enabled

test4.example.com -> 216.239.32.21
