GreatFire May: Google and Sina Adapt, The Great Firewall Strikes Back

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.

For the 16.7% of Chinese web users that use Google, the immediate effects of this was that the censorship became more transparent. To make it even more transparent, Google could choose to publish the list of blocked keywords. Meanwhile, we've reverse-engineered the full list. You can also browse our own database of keywords blocked on Google. Another effect was that the user experience improved. Since a reset connection means that you can't use the service at all for about a minute, a warning message is much more convenient. Furthermore, the suggestion function that offers autocompletion of common searches worked better. Try typing "tiananm", for example.

However, after a month of relative inactivity, this got the GFW team to strike back. Within a day, they disabled the new Google feature by blocking the javascript file that contains the code altogether. This of course makes us wonder what Google's next move will be. It would be very easy to rename the file or to embed it on the html page making it more difficult to selectively block features.

Going forward, there is much more that Google can do. Rather than just informing users that a search query has been censored, they could offer ways to get around it. The most obvious one would be to redirect users (automatically or manually) to the encrypted version of Google which is still not blocked in China (

The fact that this functionality was rolled out, and not just on Google Hong Kong but actually any Google search engine that is accessed from China, shows that Google is actively working on ways to get around censorship in China. For more on this exciting game, read Google Confronts the Great Firewall on Foreign Policy and the announcement on the Google Search Blog. was blocked in May which is the only major Great Firewall change during the month which involved Google.

How to get your account closed on Sina Weibo

On May 29, Sina Weibo announced a new user-points system to regulate users (original, interpreted by ZDNetAsia). The concept is that each Weibo user will be given 80 points to start with. Any behaviour deemed inappropriate by censors will cause points to be deducted. If the user reaches 0 points, his or her account will be closed.

Just like with the user contract announced last month, the description of what is allowed and not is very general. So what is a user who wants to get their account closed to do? Here are a few tips:

  1. Post a lot of tweets containing these keywords that are all blocked on Sina Weibo.
  2. For more efficiency, check out these keywords that are blocked not only on Weibo but also on Baidu and Google.
  3. Get some inspiration by checking out copies of thousands of Sina Weibo posts that have been deleted.

In other Weibo news, weibo: 天安门 was briefly unblocked on May 21 but has otherwise been fully blocked before and after. weibo: 郭金龙 was unblocked during the second half of May and has stayed that way since.

China Digital Times discovered many new blocked keywords. Some of them have been unblocked since, and some are blocked not just on Weibo. Here's an updated overview:

Is China establishing cyber sovereignty in the United States?

Last week Twitter came under attack from a DDoS attack orchestrated by the Chinese authorities. While such attacks are not uncommon for websites like Twitter, this one proved unusual. While the Chinese authorities use the Great Firewall to block harmful content from reaching its citizens, it now uses DDoS attacks to take down content that appears on websites beyond its borders. For the Chinese authorities, it is not simply good enough to “protect” the interests of Chinese citizens at home - in their view of cyber sovereignty, any content that might harm China’s interests must be removed, regardless of where the website is located.

And so last week the Chinese authorities determined that Twitter was the target. In particular, the authorities targeted the Twitter account for Guo Wengui (, the rebel billionaire who is slowly leaking information about corrupt Chinese government officials via his Twitter account and through his YouTube videos. Guo appeared to ramp up his whistle-blowing efforts last week and the Chinese authorities, in turn, ramped up theirs.

China is the obstacle to Google’s plan to end internet censorship

It’s been three years since Eric Schmidt proclaimed that Google would chart a course to ending online censorship within ten years. Now is a great time to check on Google’s progress, reassess the landscape, benchmark Google’s efforts against others who share the same goal, postulate on the China strategy and offer suggestions on how they might effectively move forward.

What has Google accomplished since November 2013?

The first thing they have accomplished is an entire rebranding of both Google (now Alphabet) and Google Ideas (now Jigsaw). Throughout this blog post, reference is made to both new and old company names.

Google has started to develop two main tools which they believe can help in the fight against censorship. Jigsaw’s DDoS protection service, Project Shield, is effectively preventing censorship-inspired DDoS attacks and recently helped to repel an attack on Brian Krebs’ blog. The service is similar to other anti-DDoS services developed by internet freedom champions and for-profit services like Cloudflare.

Facebook: Please, not like this

Facebook is considering launching a censorship tool that would enable the world’s biggest social network to “enter” the China market. Sadly, nobody will be surprised by anything that Mark Zuckerberg decides to do in order to enter the China market. With such low expectations, Facebook is poised to usurp Apple as China’s favorite foreign intelligence gathering partner. If the company launches in China using this strategy they will also successfully erase any bargaining power that other media organizations may hold with the Chinese authorities.

我们开发速度测试的目的是要真实反映用户的体验。当用户在网站测速时,浏览器在后台会从10个世界上最流行的网站上下载一些资源文件。根据Alexa排名,这些网站分别是Google, Facebook, YouTube, Baidu, Amazon, Yahoo, Wikipedia, QQ, Twitter and Microsoft Live。速度的结果是简单的计算下载文件文件的大小和下载所需的时间。我们同样也会验证下载的文件是否完整。如果文件的内容是错误的或者在40秒内无法完成下载,我们会标记为失败。这个数据被我们用来生成另一个重要指标-稳定性。


我们的第二个指标 - 稳定性 - 是其他的服务通常不会测试的。一个健康的互联网连接应该达到100%的稳定性,除非有人在测试中把网线拔了。但是在中国使用翻墙工具却不是这样。任何时候连接都有可能变得不稳定或十分缓慢。根据请求的大小,最终的地点和代理的方式,一些请求有可能会失败。比较服务的稳定性要比比较速度更加重要。
