On Friday 22 August 2003, Microsoft (MS) changed its DNS so that requests for www.microsoft.com no longer resolve to machines on Microsoft's own network, but instead are handled by the Akamai caching system, which, ironically, runs Linux. Akamai, one of the largest users of Linux, provides a robust, internet-wide caching system, which can act as a symmetric defence to distributed denial of service attacks. Its dependence on Linux based Akamai service proves that MS could neither persuade Akamai to use the MS-Windows operating system, nor could it find a suffciently robust service which works under MS- Windows.
Bundler of blunders : Literature (and common experience) is full of instances to show how MS-Windows has been plagued by every form of peril e.g. bugs, viruses, worms, denial of service attacks, intrusions, break-in etc., causing unmeasurable loss to users of MS- Windows based systems and networks.
Believe it or not : Microsoft.com Running on Linux

Let's see which name servers Microsoft is using right now:
microsoft.com. 1d20h7m8s IN NS DNS4.CP.MSFT.NET. microsoft.com. 1d20h7m8s IN NS DNS5.CP.MSFT.NET. microsoft.com. 1d20h7m8s IN NS DNS7.CP.MSFT.NET. microsoft.com. 1d20h7m8s IN NS DNS6.CP.MSFT.NET. microsoft.com. 1d20h7m8s IN NS z1.msft.akadns.COM. microsoft.com. 1d20h7m8s IN NS z2.msft.akadns.COM. microsoft.com. 1d20h7m8s IN NS z6.msft.akadns.COM. microsoft.com. 1d20h7m8s IN NS z7.msft.akadns.COM.
Let's do a queso on the last four.
$ sudo queso z1.msft.akadns.COM:53 220.127.116.11:53 * Linux 2.1.xx/2.2.xx $ sudo queso z2.msft.akadns.COM:53 18.104.22.168:53 * Linux 2.1.xx/2.2.xx $ sudo queso z6.msft.akadns.COM:53 22.214.171.124:53 * Linux 2.1.xx/2.2.xx $ sudo queso z7.msft.akadns.COM:53 126.96.36.199:53 * Linux 2.1.xx/2.2.xx
