From <http://uptime.netcraft.net/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.
