下载链接经常被指定到 124.202.164.* 这个 IP 段，是运营商劫持还是 CDN 部署？

    这是一个创建于 3278 天前的主题，其中的信息可能已经有所发展或是发生改变。

    我在使用 Linode 的 SpeedTest 页面的下载链接进行测速时，下载地址发生了变化，但是仍然能够正常下载。

    原地址是：http://speedtest.tokyo.linode.com/100MB-tokyo.bin
    Chrome 的下载页面显示的地址却是：http://124.202.164.4/files/118400000600AA94/speedtest.tokyo.linode.com/100MB-tokyo.bin
    下载速度有 1M/s 。

    今天下载最新版 VirtualBox 的安装文件时也遇到了这种情况。
    原地址是：http://download.virtualbox.org/virtualbox/5.0.10/VirtualBox-5.0.10-104061-Win.exe
    Chrome 下载页显示的地址却是：http://124.202.164.16/files/117900000722B058/119.147.135.245/tech.down.sina.com.cn/20151111/c50dbed4/VirtualBox-5.0.10-104061-Win.exe
    下载速度有 6M/s ，基本满速。

    如图：
    截图

    变化之后的链接地址都是 http://124.202.164.4/files/xxx 这种形式，这是什么意思？关键是下载速度都还比较快，到底是 CDN 还是什么。

    这是一种叫缓存服务器的东西 一般三方运营商和校园网布置较多
    热门文件会进服务器 进行网内传输 达到节省运营商外网流量的目的
    大概就是这样 以上都是我瞎说的

    用 wget 下载吧，有 302 重定向提示，不过电信线路应该是不会显示转向这个 url 链接的。刚想演示一下结果。。。可怜的 linode

    运营商缓存。

    不过 lz 你算是幸运的，运营商的缓存还没问题，要是赶上运营商跳转到自己的缓存、这缓存还三天两头损坏你就会想烧了运营商机房的。

    不知道你这运营商缓存会不会出现上游文件同名更新，缓存文件却不更新的情况。
