Rules:
Matchmaking is also peer to peer as far as anyone knows but I can't find any info on how messages are handled. It's entirely possible those also work on their peer to peer system but even if not a server that serves short text snippets with coordinates to all these players could be run on 20 year old hardware so not even costly enough to register.
They have literally taken down servers before for maintenance and the like.
Oh, yea, they have a verification server for shadowbans but it isn't strictly necessary for matchmaking, if that verification process were removed you can still play. The seemless coop mod for example does that.
