有时朋友向你推荐一个好网站,当你兴奋地要打开该网站时却打不开。虽有字母打错的时候,但更多的是因为浏览器被恶意程序篡改,或网通和电信互访问题,或该网站已被网关封锁甚至倒闭。所以知道该网站是否存在才能对症下药。 Sometimes a friend recommends a good website to you, but you can not open it when you are excited to open it. Although there is a typo in the letters, it is more because the browser has been tampered with by malware, or problems arise between China Netcom and China Telecom, or the website has been blocked or even closed down by the gateway. So know if the site exists to prescribe the right medicine.
