    这是一个创建于 3662 天前的主题,其中的信息可能已经有所发展或是发生改变。

    Apple 最近几年一直在推进自己的 CDN 建设,这次的 El Capitan 更新就是通过 Apple 自己的 CDN 提供的,域名 osxapps.itunes.apple.com ,大陆用户访问的话,在解析时看到的 IP 应该是下面这组:

    • 17.253.85.201
    • 17.253.85.202

    根据在国内联通和电信网络里分别 mtr 的结果,这组服务器应该是位于香港的某个 BGP 机房,并且和中国联通及中国电信都做了 peering 。所以,如果那个机房的上联够给力的话,在国内大部分地区访问的速度应该都是非常不错的。

    所以,如果你在解析 osxapps.itunes.apple.com 时得到的 IP 不是 17.253.85.* 的话,那么性能肯定是会有问题的。存在一定的几率解析到 17.253.69.*,这是 Apple 在东京的服务器,大陆用户访问的体验不会太理想。

    另外一个有趣的发现是,用于驱动 Apple CDN 的软件,并不是 Nginx / Squid / Varnish 这些常见选择,而是 Apache Traffic Server 5.3.2 :

    http://trafficserver.apache.org/

    我用上海电信的 DNS 解析出来是:
    大机率:
    17.253.71.210
    17.253.71.206

    小机率:
    17.253.85.201
    17.253.85.202

    另外一个有趣的事情是,如果你经常关注你的网站的服务器日志的话,那么,所有 17.* 开头的 IP 的访问,其实都是来自苹果公司,可能是来自苹果的搜索引擎爬虫,或者苹果的雇员(比如审核团队或者测试团队),因为 17.0.0.0/8 整个 A 段都是 Apple Inc 的。

    所以,如果你想试试改 host 大法的话,可以尝试加入下面这行:

    17.253.85.202 osxapps.itunes.apple.com

    不过要注意的是,这个 IP 只对 Apple 新的这些用于服务大文件和媒体下载的域名有效。而对以前的那些域名,尤其是那些 SSL 流量,是没有配置的。

    从香港做大陆 CDN 的话,这成本不低啊
    不知道像苹果这样的海外大公司在国内建点自建 CDN 的话要不要 ISP 证,要的话很难批吧
    Google 号称要入华这么久,现在也没信儿了,估计是没给他批,或者没有国内的二道贩子敢接他
