网站打开慢常规问题排查

如果有遇见网站访问慢，建议首先从以下几个方法检测一下，是否是服务器配置或者网络的原因

1. 检查域名解析是否正确，我司虚拟主机默认推荐做别名解析到赠送的二级域名（xxxxx.gotoipx.com）

特别注意（西部双线、多线机房）此机房是通过CDN实现的双/多线，如果是做的A纪录会造成联通和其它线路打开慢

必须做别名解析到我司赠送的二级域名上面，顶级域名不能做别名的，可以解析到Ip后做一个301跳转到www域名上面

另:我司的域名支持顶级域名做别名解析

2. ping一下您的域名，看看延迟是否正常（开始-运行-CMD回车）

如果时间值大于100，则网络连接质量有异常，此时如果您购买的是单线主机，请核实您主机线路和您当前本地线路是

否一致，如果不一致，建议升级到多线或者双线主机，如果您当前已经是双线或者多线，请把此图提交到工单中，

方便我司技术检查处理

3. 如果非上述两个原因，则可能是服务器异常或者程序异常，具体请联系程序员或者提交工单，我司检查原因

常用公共DNS服务器地址

威海网站建设威海dns
2585

DNS，全称Domain Name System，即域名解析系统，帮助用户在互联网上寻找路径，它在互联网的作用是把域名转换成为网络可以识别的IP地址。目前国内电信运营商通过使用DNS劫持和DNS污染的方法，干扰用户正常上网，使得用户无法访问众多国外常用服务，因此今天我介绍一些国内外的公共DNS服务器地址，供大家选择使用。国外公共DNS服务器地址Google Public DNS （8.8.8.8，

决定网站访问速度的几个因素以及优化方向

第一，主机线路和地区的选择。我国存在多个不同网络服务商，比如电信，联通，教育网，移动等。不同线路直接访问会有互联互通不稳定的情况发生，一般建议选择BGP机房线路，访问会更均衡一些。另外国内访问境外由于存在国际出口相对访问也比较慢，国际带宽出口资源通常比较紧张，时常会有拥堵缓慢的情况。若针对的是香港用户可以考虑港台机房；若针对欧美用户，建议使用我司美国主机。第二、主机的配置和访问量是否匹配服务器的配
