No one runs servers with Windows 3.1. They would have used Windows NT.
The really damning bit is Windows 3.1 did not have preemptive multitasking. It barely had networking. You couldn’t run a server with it if you wanted to.
That is fair. I wasn't aware of the kerfuffle around whether Southwest was using 3.1 or not. I took the source and linked source at face value. It would have been nice to have had someone do more than "nope" and instead link to a reputable source. This is how you counter disinformation.
Southwest wasn't affected because they don't use Crowdstrike. That's it.
