Yahoo.com is a consistent FreeBSD on their servers. Apple.com which is known for OSX as based in Unix is not surprising to see MacOSX and Linux running on their servers. The most surprising part is when I looked for Microsoft.com statistics and found out that they are running Linux on some of their web servers. The irony is that Microsoft is attacking Linux as an insecure OS which can be found on their Get The Facts campaign."
