That doesn't mean the server isn't working. it's neither offline, fixing, or updating. and, this will be helpful, before you post, check posts above you. And more importantly, check the title of the thread. it said 'NOT 24/7' and 'CAN'T afford VPS'. not an insult or an offense to you, just a compliment.
what I just said above may seem aggressive, but really, i'm not angry at all.
anyway to all other users who keeps wondering why people post private servers that don't even work, this would be good advice to you so you don't have to worry too much or keep thinking it as a faulty server.
hope this will help.
