On April 1, 2015 Google announced that they will no longer recognize the CNNIC Root and EV (extensive validation) certificate authorities (CAs).
On April 2, 2015 Mozilla concluded that CNNIC’s behaviour in issuing an unconstrained intermediate certificate to another company was ‘egregious practice’ and that Mozilla products would no longer trust any certificate issued by CNNIC’s roots. Mozilla also published a more detailed report about their actions.
After unauthorized digital certificates for several Google domains were exposed by Google and Mozilla on March 23, 2015, CNNIC censored any mention of these posts. CNNIC is not only a certificate authority, they are also China’s online censorship apparatus. CNNIC was, is and will continue to practice internet censorship.
News about the April 1 and 2 annoucements has again been censored on social media and also on traditional media in China.
Below is a screenshot of Weibo posts about these announcements.

The Great Firewall has switched from being a passive, inbound filter to being an active and aggressive outbound one. This is a frightening development and the implications of this action extend beyond control of information on the internet. In one quick movement, the authorities have shifted from enforcing strict censorship in China to enforcing Chinese censorship on internet users worldwide.

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.

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.

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:
