Google access?
Wednesday, May 31st, 2006From Beijing, access to www.google.com has been spotty the last 36 hours from my home DSL connection, and is now completely inaccessible. Hope it’s just a temporary glitch, but will try it from other connections around Beijing later. This might be related to a famous upcoming anniversary.
UPDATE (12:40pm) - Seems this is not isolated. Tests from a coffee shop with a public Internet terminal (a) and hotel with open wifi (b) show similar results in Beijing, and is confirmed by various reports from others in Shanghai and Guangdong - “www.google.com.” is inaccessible in significant parts of the PRC. Curiously, no other major search engines are affected, and “www.google.cn”, “news.google.com” and “mail.google.com” are accessible.
(a) IP: 222.128.xxx.xxx
ASN: 4814 [CHINA169-BBN (CNCGROUP IP network¡ªChina169 Beijing Broadband Network)]
Near: Beijing, Guangdong(b) IP: 218.106.xxx.xxx
ASN: 17620 [CNCGROUP-BJ (CNCGROUP IP network of Beijing region MAN network)]
Near: Beijing, Guangdong
Caveat: Results are coming from Beijing and one particular ISP (CNC). Results may vary by locale and provider. One person pointed out that this might just be an accidental glitch in the installation of a new phase of the Great Firewall. As you can see, diagnosing the GFW is particularly tough.
UPDATE (1:00pm) - Added “www.google.cn” to list of OK sites. Tuned the wording, adding, “in significant parts of the PRC.”
UPDATE (1:50pm) - A workaround has been found for now. The problem is that “www.google.com.” resolves like this when using CNC’s name server (using the dig utility):
;; ANSWER SECTION:
www.google.com. 603287 IN CNAME www.l.google.com.
www.l.google.com. 79 IN CNAME www-china.l.google.com.
www-china.l.google.com. 25 IN A 66.249.89.99
That IP address is the problem as something (GFW?) breaks the connection when the HTTP headers are being sent back to your browser. However, if you do a DNS lookup of “www.google.com.” outside of China, you’ll find other addresses. The following two worked for “Google English”:
Try these two, and it should work.
UPDATE (2:30pm) - For now, it appears “http://www.google.com” works again, as the 66.249.89.99 IP address seems to go through. Keep those two IP addresses above handy though.
UPDATE (2:55pm) - Though “www.google.com” is back, seems that “news.google.com” is now inaccessible with the headers problem. In advance of the fourth of this month, I’m sure there will be other ups/downs for web sites outside the PRC.
UPDATE (3:00pm) - Seems both “www.google.com” and “news.google.com” are inaccessible. The “hack” above for using the raw IPs will get you to “www.google.com” but to access Google News, you will have to hack your hosts file (Windows) or /etc/hosts file (Mac and Linux). Put an entry like this:
216.239.37.104 news.google.com
into the appropriate place in your operating system. See the following directions: for Windows and Mac. (The 216.239.37.99 address above seems to be inaccessible now).
