Does anybody knows or have any info about the OS of the servers of World of Warcraft?
I have a "debate" with some friends about the OS behind WoW. They say it could be Win, which is very strange for me.

Most MMOs use Windows for servers mostly because of Visual Studio. VS is basically the only development and debugging environment that is worth its salt (cue *nix users saying that gdb is just as powerful as VS). This means that we all are generally developing both the clients and servers on Windows, so it is just easier to also deploy on Windows. There are some out there that will cross-compile the servers for production (clients are clearly always targeting Windows at the very least, even if you have a Mac version) but it ends up being a hard thing to maintain and it makes debugging production systems that much harder. The big exception is web-based games, those are almost always Linux based (and usually running Apache and/or Nginx).
