Hmm. I think my confusion comes from the assumption that each "fortress" (server) is a virtual server hosted by ctf365. From their rules: Don't try to conduct underground activities with your Fortress (system) from our platform in the Real World (e.g. using our platform to spam others, attack other servers on the internet and so on). We don't care who you are, but we do care what you are doing in our home (CTF365 Platform). Please remember that you are our guest and please behave accordingly. I read this to imply that they will provide the "fortress". So when I say "sandboxed" system, I mean a system provided by ctf365 on their own infrastructure - infrastructure which permission is implicitly granted to attack.
