用ping命令测试到目标主机是连通的有正常的返回数据，钽是网页打开。网络没有问题其它的网站都可以打的开.
这里我想问个问题就是TCP连接超时没有得到对方的确认会重复连接几次然后不在连接啊?

我昨天晚上10点至11点左右也是打不开，感觉应该是应用层的问题，服务器出问题了
www.csna.cn用的是 Apache/2.0.54 (Fedora)  PHP/5.0.4的服务器

当时PING包好像延时也不是很大
C:\Documents and Settings\Administrator>telnet www.csna.cn 80
正在连接到www.csna.cn...不能打开到主机的连接， 在端口 80: 连接失败

C:\Documents and Settings\Administrator>ping www.csna.cn -t

服务器响应时间很慢
不会是遭攻击了，要不是服务器性能不够好

是怎么会事站长应该很清楚
