Wow!!! OMG! Running a Server Costs Moulah [money]. Maybe He didn't have enough money to pay for skywars. Maybe it switched to some complete random server. Maybe he lost it in poker WHO KNOWS! i mean it couldn't be gone forever when its a sky server... right?
Well, many people buy things from the servers each day = more money. And Cyp wouldn't bet in in poker.
My theory is that Noob didn't have enough money to pay for the server at the end of April so he took down Skywars until the server was making enough money to pay for it again.
What actually happened was the save file for the server got messed up somehow and Cyp is very sorry for that (he really did say that I just can't find the post).
