为什么www.yahoo.com无法访问？
从昨天中午，我发现www.yahoo.com无法访问, 问了多个北京和上海的朋友，结果一样。
IE提示“无法显示该页”，“找不到服务器或 DNS 错误”。
Firefox提示“连接超时”。
ping一下域名，DNS解析没有问题：

今天上午，去看mail.yahoo.com时，顺便打开了一下www.yahoo.com，发现可以访问，而现在又不可以了。
2006.11.07 13：40 又可以访问了。
印象中www.yahoo.com一直非常稳定，而这段时间不太稳定的www.msn.com和www.google.com此时却都可以访问，yahoo中国cn.yahoo.com也一样可以访问。而以yahoo目前在中国的策略也不会遇到像Google那样的GFW问题，难道像此前盛传MSN大面积瘫痪是因为技术问题或者是硬件问题？
还有，目前在baidu和google上搜索一下，没有发现有人关注此事，奇怪。
我最近连续两次遇到flickr无法登陆，即login.yahoo.com无法打开，不知道怎么搞的。
奶奶的！这种现象持续一年多了！怀疑被中国的那些奸商们给屏蔽了！因为使用代理服务器是可以上雅虎英文站点的！
