Microsoft.com is run on IIS6 with Windows Server 2003 http://www.microsoft.com/backstage/inside.htm Akamai provide a content distribution network and dns to get download files closer to end users to improve the overall end user experience by speeding up file downloads. http://uptime.netcraft.com/up/graph?site=www.microsoft.com reports that MS is running IIS6 on Linux! How is that possible? http://uptime.netcraft.com/up/accuracy.html#impossible Why do you report impossible operating system/server combinations ? Webservers that operate behind a caching system, load balancer, reverse proxy server or a firewall may sometimes report the operating system of the intermediate machine. Hence reports of 'Microsoft/IIS on Linux' may indicate that either the web server is behind a Linux server that is acting as a reverse proxy, or has configured the Akamai caching system such that the first request to the site goes to one of Akamai's servers [which run Linux], or as in the case of www.walmart.com has been configured to send a misleading signature. -----Original Message----- From: Juha Saarinen [mailto:juha(a)saarinen.org] Sent: Saturday, 16 August 2003 9:12 a.m. To: Joe Abley Cc: nznog(a)list.waikato.ac.nz Subject: Re: [nznog] microsoft.com Joe Abley wrote:
That power outage knocked out bits of the North Eastern US and most of
South-Western Ontario (including my house -- still no power here, just
laptops and cellphones). To the best of my knowledge most Microsoft-branded services are served out of Redmond, and Hotmail is in the Bay Area somewhere (used to be in an MFN/AboveNet facility in San Jose, but I seem to remember they moved a while ago).
Most large exchange facilities in New York seem to have survived on battery and diesel power, and I don't believe the outage stretched as far as Virginia (where it might have stood a fighting chance of impacting some high concentrations of network operators).
So probably not related to the power outage.
It's also interesting to note that a good chunk of Microsoft's Web content is served from Linux boxes. "Akamaighost" apparently runs on Linux. Here's an example: http://uptime.netcraft.com/up/graph?site=a100.ms.a.microsoft.com Looks like Windows Update arrives to you via Linux as well. -- Juha _______________________________________________ Nznog mailing list Nznog(a)list.waikato.ac.nz http://list.waikato.ac.nz/mailman/listinfo/nznog
