Google.com blocked in China

Today, Nov 9, 2012, http://www.google.com and http://www.google.com.hk were blocked in China. It's the first time since we started tracking online censorship in China in February last year that this has happened. Here's what we know:

  1. The subdomains http://www.google.com, http://mail.google.com, http://google-analytics.com, http://docs.google.com, http://drive.google.com, http://maps.google.com, http://play.google.com and perhaps many more are all currently DNS poisoned in China. Instead of the real IP addresses, any lookups from China to any of these domains result in the following IP: 59.24.3.173. That IP address is located in Korea and doesn't serve any website at all.
  2. This means that none of these websites, including Google Search, currently work in China, unless you have a VPN or other cirumvention tool.
  3. Using a DNS server outside of China doesn't help. A lookup of www.google.com to 8.8.8.8 is also distorted, by the Great Firewall.
  4. So far you can still access other country versions of Google such as www.google.co.uk.

You can see an overview of different Google sites here: https://en.greatfire.org/search/google-sites. You can choose any of them and test them in real time to stay updated.

Affecting more users than ever

Facebook, Twitter and YouTube were all blocked before they attracted more than a small number of users in China. We've argued before that the authorities didn't dare to fully block GMail since it has too many users already. Fully blocking Google goes much further. Google Search is only the second search engine in China (after Baidu) but with an online population of more than 500 million that still leaves it with many millions of daily users. According to Alexa, it's the Top 5 most used website in China. Never before have so many people been affected by a decision to block a website. If Google stays blocked, many more people in China will become aware of the extent of censorship. How will they react? Will there be protests? Check out reactions by Weibo users on FreeWeibo

Temporary or permanent?

The Communist Party of China is currently holding its 18th Party Congress in which new leaders of the party and the country are formally chosen. The fact that Google is blocked now is surely no coincidence. The big question is whether it will be unblocked again once the congress is over. We will closely monitor developments. 

By the way.. Analytics

The fact that http://www.google-analytics.com and https://www.google-analytics.com are blocked doesn't just mean that you can't access the web interface in China. It means that visits by Chinese users won't be tracked by Google anymore. Foreign websites using Google Analytics to track their visitors will currently track 0 users coming from China, whether or not their website itself is blocked.

What to do?

Many VPNs and other circumvention tools have been working poorly or not at all in the last few days. The free iPhone app OpenDoor is still working, though it has also suffered glitches recently. Another method of accessing Google Search is to use one of their other country versions such as http://www.google.co.uk https://www.google.co.uk or http://www.google.ca https://www.google.ca. These may also be blocked of course.

You can also access Google directly using one of their IP addresses. These don't appear to be blocked (yet). Here are some:

CNNIC censors news about their own statement

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.

Chinese authorities compromise millions in cyberattacks

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.

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.

my biggest beef is that translate.google.com was also down for quite significant amount of time. Now, since I was a mere mortal without sophisticated network monitoring algorithms at hand, trying to do some work, i couldn't tell how long it was out for. But i swear that it was down for quite some time. Which was pissing me off -- i mean, translate.google.com. Are you serious???

I believe you're right. Since China poisoned "*.google.com" which would also match translate.google.com subdomain.

Thanks for your workarounds. However, none work at this time, November 12, at 20:42
