Event Server Not Showing

[MysteriaParade]

I was recently looking through the forums and found an event that seems fun and that I may like to attend taking place on the event server. The problem is, the event server does not show up on my server list. I used to have this problem with the build server and v2p, but I had joined a friend playing on one of those servers and when I left the game it remained on my list. I believe the other time I had gotten the IP from someone. 
If someone know how to fix this or maybe knows the IP, that'd be great. Thanks.

You can only join when allowed to by a administrator, and to run/partake in a event. The server is turned off to prevent abuse of it and to give more space towards the other servers (2d, 33x, 2p)

It will be turned on for the event you are wishing to join if a admin has accepted it.
