怎么知道国外主机空间是否被屏蔽及解决方案

原文:http://greenhandtobe.blogspot.com/2012/06/blog-post.html

买主机空间之前没有调查是不是被墙了,把做好的站点挂上去了才发现国内上不了,郁闷。。。

先写写经历吧。

1. 挂上网站后被人告知打不开,用国内的代理IP才发现确实被墙了……于是接下来首先确定是不是网站使用的主机的IP的原因。

2. 在System->Administration->Network Tools中选择Ping (Ubuntu下的,Windows下用cmd),Ping网站的域名,就知道IP地址了。

3. 在whois提供的信息里搜这个IP,得知这个IP上存放的为数众多的网站。(可以Ping它们确定一下。)

4. 用不同的代理去踩这些跟自己网站同IP的网站(直接用自己的Ping也可以),如果所有同IP的网站表现一致,恭喜你,这个IP因为host了某些某些人不喜欢的网站,它host的所有网站都被墙了。



然后关于解决这个问题:

1. 最好的方法当然是买独立IP,就不用担心受其他因素的牵连了。常用的买独立IP的地方有GoDaddyIxWebHosting,GoDaddy比较贵但是比较稳定,IxWebHosting很便宜不过不是很好用。

2. 不过如果没有太多预算,又不想浪费之前购买的空间呢,还可以尝试用CDN服务。这是个从你原地址中获取数据,再分配给用户的中介,由于是为了资源优化配置,所以还可以提高网页浏览速度。常用的提供CDN服务的比如CloudFlare,提供免费的服务,而且页面很简洁。再比如WebLuker,可以自己找找,多比较一下。一般提供CDN服务,只需要你注册,提供域名,它会给你分配一个Name Server (NS),你只需要在你的域名提供商的帐户上修改成它给你提供的NS就可以了。
