China: Ping…ping…pfft · Global Voices
John Kennedy

The earthquake near Taiwan last night which snapped six underwater internet cables, seems to have left a large part of Asia, particularly the Northeast, struggling for an internet fix.
Those with internet censorship circumvention tools (proxies) already installed on their computers seem to be doing a little better, but for Hong Kong and mainland China, access is now mostly limited to local sites, but even those have been affected as well. China's largest internet portal website Sina.com's blog site shows almost no mention of the earthquake or the blackout, and RSS feeds slowed to a trickle around lunch time today. MSN and Yahoo! Messenger have been affected as well, although QQ and GTalk are operating normally. Phone calls to other continents, some bloggers are saying, don't connect.
A post from independent blogger Wang Pei shows that not only are Chinese netizens stuck inside the region, but Chinese websites and users seem to have disappeared off the map as well:
热烈祝贺大中华局域网今天测试
今天英国、日本网友无法连通国内网站，新浪、网易统统上不去。MSN上也见不到几个人。不知道其他国家网友能否访问。
一个可能的解释，大中华局域网正在测试。中国正在变成一个大网吧。
什么是大中华局域网？
“What is the ‘Greater China LAN'?” Wang asks, with a link to fellow indy blogger He Caitou's post on a partnership between China Netcom and American company Verisign which was announced last week, to install root server mirroring (.cn) in China.
Followed by two later updates:
遇到一样情况的网友同样来自：美国，新西兰。
我拥有300多联系人的MSN上，现在上线的只有5个人，而平常至少是这个数字的10倍。
From Hexun blogger zyx105106107 attempts to decipher the reason MSN can't be logged into on his internet service provider, China Netcom, mentioned in the post above above, which he links to the earthquake.
今日凌晨起，部分国外网站无法正常访问，其中包括雅虎在内的多家国际门户网站，而“MSN”、“雅虎通”等即时通讯工具也无法正常登陆。经证实，台湾地震导致中国网通国际互联网出口出现故障。
网通公司答复：目前技术人员已经确认，由于台湾地震导致中国网通国际互联网出口出现故障，国内用户无法登陆部门国外网站。
