一直以來，有很多人抱怨 Hinet 下載 Windows Update 就是特別慢，這都是因為 Hinet 沒有與 Akamai 公司合作所致，因此就在11/06 我心血來潮的寫信給呂董抱怨這個問題，沒想到居然有善意的回覆，而今天查詢了一下 DNS，也過去了！下載 Windows Update 非常的快了，這是 100KBytes 和 1MBytes 的差別啊！
測試檔案：Visual Studio 2008 SP1
以下為 2009/01/19 的測試結果，是國內的 IP 了！！！
========================================================
thkuo@thkuo-laptop:~$ nslookup download.microsoft.com dns.hinet.net
Server: dns.hinet.net
Address: 168.95.1.1#53
Non-authoritative answer:
download.microsoft.com canonical name = download.microsoft.com.nsatc.net.
download.microsoft.com.nsatc.net canonical name = main.dl.ms.akadns.net.
main.dl.ms.akadns.net canonical name = intl.dl.ms.akadns.net.
intl.dl.ms.akadns.net canonical name = dl.ms.d4p.net.
dl.ms.d4p.net canonical name = dl.ms.georedirector.akadns.net.
dl.ms.georedirector.akadns.net canonical name = a767.ms.akamai.net.
Name: a767.ms.akamai.net

以下是我在 2008/11/06 的分析結果，紅字代表國外的 IP，藍字代表國內 ISP 所屬 IP。
分析結果顯而易見的是 Hinet 國內下載流量錯誤地引導至國外 Akamai 主機，造成了下載異常緩慢，亦造成國際頻寬浪費的情形。
