这是一个创建于 3584 天前的主题，其中的信息可能已经有所发展或是发生改变。
今天打开网站发现部分图片不显示，用 360 浏览器的“审查元素”功能发现不能显示的图片前被加了“ http://120.52.72.70/”前缀，比如：
原本图片地址是： http://aliyun.youhuima.cc/c3pr90ntcsf0/wp-content/uploads/2015/12/500-300x218.jpg ，网页 html 代码查看也是这个地址
但实际是 get 的这个地址： http://120.52.72.70/aliyun.youhuima.cc/c3pr90ntcsf0/wp-content/uploads/2015/12/500-300x218.jpg
网站没有开启 CDN 。查了 120.52.72.70 归属，发现是联通云数据公司，我用的是联通宽带。这是被联通给 CDN 了吗？还是别的原因。
