Google.com 在中国被封锁

今天, 2012年11月9日, http://www.google.com http://www.google.com.hk 在中国被封锁. 这是从去年2月我们开始监测中国审查以来第一次看到这种情况。以下是我们知道的信息:

  1. 子域名 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 等在中国被DNS污染. 若用户在中国进行DNS查询,用户不会得到真实的服务器IP地址,而得到一个伪造的地址 59.24.3.173. 这个IP地址在韩国,没有任何网站和这个地址有关联.
  2. 这意味着Google的任何网站, 包括谷歌搜索, 在中国的无法被使用, 除非你使用VPN或者其他翻墙工具。
  3. 使用境外的DNS服务器也没用帮助. 在8.8.8.8 DNS查询 www.google.com 也会被中国防火墙污染。
  4. 到目前为止,你仍然可以使用其他国家的谷歌搜索,比如 http://www.google.co.uk.

你可以在这里浏览Google站点的封锁情况: https://zh.greatfire.org/search/google-sites. 你可以选择任何一个网站,并且对其进行实时测试。

影响用户数量史无前例

Facebook, Twitter and YouTube 在中国用户数量还不多时就被中国封锁. 我们认为因为Gmail已经在中国有大量用户,所以中国政府不敢对其进行封锁.对Google进行全面封锁是更进一步了. 虽然谷歌搜索只是中国第二大搜索引擎 (百度第一) ,但中国网民有5亿,谷歌仍然有上百万活跃用户. 根据 Alexa, 谷歌是中国第五大网站. 一个网站被封锁从来没有影响这么多用户. 如果谷歌持续被封锁, 许多中国用户会注意到中国互联网审查的严厉程度. 网民会对此封锁作出如何反应? 会有抗议么? 访问 FreeWeibo来关注中国网民对此事件的反应.

暂时还是永久?

中国共产党正在举行中国共产党第十八次全国代表大会,在大会上党和国家的新一届领导人会被正式选举产生. Google在这期间被封锁不是偶然. 重要的问题是对Google的封锁会在大会闭幕后结束么?我们会全力监测事件动态

别忘了.. Analytics(分析)

 http://www.google-analytics.comhttps://www.google-analytics.com 被封锁不仅代表了你不能访问Google分析的后台,这还表示来自中国的访问者不再被Google分析追踪. 使用Google分析来追踪用户的网站会看到0个用户正在访问你的网站, 无论此网站在中国是否被封锁.

如何应对?

许多VPN和翻墙软件在这些天工作异常活根本不工作. 免费的iPhone应用 OpenDoor 还能使用, 虽然它也偶尔不能访问. 另一个访问Google的访问是访问其他地区的Google,比如 http://www.google.co.uk https://www.google.co.uk 或者 http://www.google.ca https://www.google.ca. 这些域名在未来当然也可能被封锁。

你也可以使用IP地址来直接访问Google. 它们至今未被封锁. 以下是部分IP地址:

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.

给鲁炜和中国网信办的公开信

2015年1月26日

中国,北京。

鲁炜先生:

在2015年1月22日, 您领导的中国网信办对我们发表的Outlook在中国遭中间人攻击的文章进行了公开回应。 在中国网信办的公开回应中,您的同事姜军说我们的指责是“无端臆测,纯属境外反华势力的造谣和污蔑“。

我们GreatFire.org成员对中国网信办的评论非常愤怒,我们在本公开信中逐条驳斥。

我们没有轻易指责中国网信办。我们收集了大量数据来支持我们的结论。很多报告都支持了我们的分析,包括了截图许多中国网民的报告和其他技术人员的独立分析

我们之前报道过对iCloud,雅虎,微软和谷歌进行的中间人攻击,每个公司都确认了中间人攻击的真实性。我们还邀请了其他技术人员对攻击数据进行了独立分析。 你可以阅读对每次攻击的独立分析: OutlookiCloud谷歌雅虎Github 。 每个分析结论都类似:

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
