EDIT: ClubPenguinV is back online.
ClubPenguinV is down, due to a recent DDoS (Denial of Service Attack) by an unknown party. Many people are speculating that the culprit was possibly (a) staff member(s) of a current Club Penguin private server who want the advantage of more users if ClubPenguinV is offline. Currently their entire website is down (which includes the ‘Play’ version).
The ClubPenguinV staff is calling it ”server upgrades”, however I have heard from multiple sources that it was indeed a DDoS attack.
Either way, I’ll let you know when it’s back online.
