什么是网络连接超时?

网络连接超时意味着用户的网站请求被中国防火墙(GFW)刻意干扰,无法得到目标网站的响应,从而无法加载目标网页。这时,浏览器会显示如下信息:网络连接超时。若没有翻墙(墙即GFW)工具,用户将无法判断这是网站服务器出现问题,还是GFW的干扰。因而,多数用户都把连接超时的问题归咎于目标网站自身。

本站基于以下条件判断网站的连接超时是由GFW 所为:

  1. 在美国访问目标网站,网站请求在15秒内得到服务器响应
  2. 在中国访问目标网站,网站请求超过15秒无响应。

Today, I went to the beach front with my kids. I found a sea shell and gave it to
my 4 year old daughter and said "You can hear the ocean if you put this to your ear." She put the shell to her ear and screamed.
There was a hermit crab inside and it pinched her ear.
She never wants to go back! LoL I know this is entirely off
topic but I had to tell someone!
