Did the CoH servers use Windows Server 2003 as their operating system?
At one point I thought they used Linux visualizations under IBM System z, but then I came to my senses and realized that would be some way expensive overkill if they did that. Then I recall a post made where one of them mentioned server maintenance also included Windows Update, or at least I remember it that way.
I'm asking mostly because I'm curious. Though I guess if the servers were ever going to go back online, they'd have to use a less outdated operating system, haha.
I'm pretty sure they would have been using 2008 by the time of the shutdown, but yes, it was a flavor of Windows.
