App Store国内有CDN了？

[mtglichking]

网络环境北京联通，刚刚在App Store下载速度能赶超迅雷离线的速度。。。

Terminal 里运行 dig a1.phobos.apple.com 看看就知道了。

@Livid 呵呵，还是用的蓝讯的

Non-authoritative answer:
a1.phobos.apple.com canonical name = a1.phobos-apple.com.akadns.net.
a1.phobos-apple.com.akadns.net canonical name = a1-a200.phobos.apple.chinacache.net.

@ninjai
这个是表示一条CNAME链么？还是平行的？

[Livid]

@ewangke Yes, a CNAME chain.

为啥手机用wifi超级慢，速度在1K以下，基本没法正常下载，用3G和电脑都很快，应该如何解决啊

[hh4j]

我这默认当地联通DNS下载很慢，用了v2ex能快些了，目前Apple的CDN并没有感觉出来有多快。

[bostoneboy]

深圳电信，确实有国内CDN加速了。于是把这个域名加到dnsmasq里面了
