www.google.com访问不了是怎么回事？(已经恢复)

好像以前还没有出现这样的问题，www.google.cn可以正常访问，但是www.google.com却不能访问，这样的话最常用的Google Reader、Google Adsense、Google Account都就访问不了了。这到底是怎么回事呢？很纳闷。

ping一下www.google.com这个主机地址，www.google.com解析到别名www-china.l.google.com这个地址上了，丢包率是100%，根本Ping不通：

C:\Documents and Settings\LXJ>ping www.google.com

Pinging www-china.l.google.com [64.233.189.104] with 32 bytes of data:

Ping statistics for 64.233.189.104:
    Packets: Sent = 4, Received = 0, Lost = 4 (100% loss),

而www.google.cn这个地址则能正常访问，ping结果如下：

C:\Documents and Settings\LXJ>ping www.google.cn

Pinging cn.l.google.com [203.208.37.99] with 32 bytes of data:

可以看出www.google.cn这个域名解析到cn.l.google.com这个主机上了，cn.l.google.com 这个主机可以正常访问。

再ping一下Google.com这个域名：

C:\Documents and Settings\LXJ>ping google.com

Pinging google.com [64.233.167.99] with 32 bytes of data:

从Ping结果来看，Google.com丢包率还是有的，说明Google.com的服务器在中国不是很稳定，为什么会出现这样的问题呢？很想知道，不知道大家能不能正常访问www.google.com呢？

刚刚用代理上www.google.com，可以正常访问，说明www-china.l.google.com这个服务器在中国被暂时禁止，或是出了问题了。希望能尽快恢复。

UPDATE：今天早上已经恢复了。Ping结果如下：
