Game servers in a professional / commercial context. Absolutely no hobbyist questions.
Questions regarding game servers in a professional context only (e.g. by game companies or commercial "as a service" offerings).
This excludes any and all hobbyist questions (e.g. "I want to run a Minecraft server for my friends and me") which might be on topic at Game Development SE or Arqade. Arqade has many Minecraft server questions already that may cover what you are trying to do.
