今天从Google 搜索到了ubunut.com的网页,看起来很假的域名,是不是就是假的?激起了我的好奇心。
Google ubunut.com 虽然会建议你搜索ubuntu.com,但是搜出来的东西也是通常情况下的访问量较大的url,如下图:
查whois信息。
下面是ubunut.com的:

光从DNS Servers列表看就不是假的, canonical不会傻到对假域名解析。
奇怪的是,ubunut.com又不是对ubuntu.com域名简单的redirect一下。对比两个主页(ubuntu.com vs ubunut.com),特别是下载页(ubuntu.com vs ubunut.com),显然ubunut.com是ubuntu.com的老版本页面。
ubuntuforums.org 对两个ubunut.com的存在进行过讨论。在没有得到官方答复的情况下,分析原因有一下几个:
- ubunut.com是在不同服务器下,对ubuntu.com整站进行了备份。
- 为何不同步?为了让主站被搜索引擎得到更好的索引
