GreatFirewall.biz blocked by, ehem, the Great Firewall

Dear reader. I know something about you. You are either not in the People's Republic of China - or you are using a VPN or proxy to bypass the Great Firewall. Otherwise, you wouldn't be reading this. Since yesterday, this website has been added to the list of websites blocked in China. As you can see to the right, other websites with information about the Great Firewall are blocked too.

Why, oh why?

Chinese people don't need this website to test whether a website is blocked or not - they can simply type in a URL or search and if it's blocked, the connection will be reset or timeout. Or do they? When a website doesn't work, it could be because it's blocked, but it could also be caused by the website itself. How can you tell the difference? You can connect your VPN and try again - or, you can test it on this website. A website is only marked as blocked by us if it 1) works when accessed from the US and 2) does not work when accessed from China.

Take, for example, the current difficulties of accessing Gmail in China. Our monitoring shows that this is caused by the Great Firewall - but the government has denied this and seem to want people to think that the problem lies with Google. Isaac Mao, a Chinese blogger, commented that the government is "testing the tolerance of the people" adding that "they cannot block Gmail totally, at this moment, because millions of people are using Gmail. If it is found that the government did this, people will react even more".

Indeed. So the government is doing what it can to prevent people from finding out.

One of the oddest rumours out there is that Gmail isn't working because the servers are located in earthquake-hit Japan...

CNNIC censored Google and Mozilla’s posts about CNNIC CA

This week, Google found unauthorized digital certificates for several Google domains, the root CA of which is CNNIC. Google and Mozilla both publicly disclosed this security incident and published blog posts(Google, Mozilla). However, Chinese translations of Google’s and Mozilla's blog posts were censored on the Chinese Internet.

  • William Long is a prominent Chinese blogger on IT and tech. He translated Google’s security post without adding any personal opinions. The Chinese blogpost ranked #1 when searching CNNIC MITM in Chinese on Google and Baidu. He tweeted that he received a phone call from propaganda department demanding the post to be removed immediately. The post http://www.williamlong.info/archives/4183.html was deleted. Google cache is still available.

Evidence shows CNNIC and CAC behind MITM attacks

Since 2013, we have repeatedly called on major software vendors to revoke CNNIC-issued certificates. Most notably, we raised this issue when we reported on the Cyberspace Administration of China’s (CAC) man-in-the-middle (MITM) attacks on Google, Microsoft’s Outlook, Apple, Yahoo and Github. Mainstream media have reported about these security vulnerabilities before and on March 24, Ars Technica reported on Google’s announcement that they have definitive evidence that CNNIC (China Internet Network Information Center) was behind a new MITM attack on Google.

From our October, 2014 blog post:

We are under attack

We are under attack and we need help.

Likely in response to a recent story in the Wall Street Journal (WSJ), we’ve experienced our first ever distributed denial of service (DDoS) attack. This tactic is used to bring down web pages by flooding them with lots of requests - at the time of writing they number 2.6 billion requests per hour. Websites are not equipped to handle that kind of volume so they usually “break” and go offline.

This kind of attack is aggressive and is an exhibition of censorship by brute force. Attackers resort to tactics like this when they are left with no other options.

We are not equipped to handle a DDoS attack of this magnitude and we need help. Some background:

  • The attack started on March 17 and we are receiving up to 2.6 billion requests per hour which is about 2500 times more than normal levels.

Collateral Freedom and the not-so-Great Firewall

Recognizing that the authorities have been hesitant to crackdown on our method of circumvention, we have accelerated our expansion of the development of collateral freedom, in three key areas.

An Open Letter to Lu Wei and the Cyberspace Administration of China

January 26, 2015

Beijing, China

 

Mr. Lu Wei

Director of the Cyberspace Administration of the People’s Republic of China 中央网络安全和信息化领导小组办公室主任

Director of the State Internet Information Office 国家互联网信息办公室主任

Deputy Director of the Central Propaganda Department of the Chinese Communist Party 中共中央宣传部副部长

Cyberspace Administration of China,

Floor 1, Building 1,

Dear Mr. Lu,

On January 22, 2015, the Cyberspace Administration of China (CAC), which is under your direct control, wrote a response to a story we published about an MITM attack on Microsoft. In the post, your colleague, Jiang Jun, labelled our accusations as "groundless" and  "unsupported speculation, a pure slanderous act by overseas anti-China forces".

We at GreatFire.org take great offense to these comments and we will refute them in this letter.

Our own tests, linked in the Related list top right on this page, confirm that this website has been unblocked in China. Yay, we're open for business again!

We were unblocked for three days, now blocked again..

If you aren't home much, have children under the age of ten,
don't enjoy chaos, or have a busy lifestyle which
would prevent a ferret from roaming freely, then these pet
