Umm, since the restart, I can't join the server. And I don't think anyone can because it seems like something like 30 people are online all the time...
The lobby is apparently down which is why you cannot join. Use the IP's below to join the server, but not the lobby and if you wanted to switch to different minigames use the /server command. IP's: - sg.itsjerryandharry.com - buildit.itsjerryandharry.com - oitc.itsjerryandharry.com Also, if you look in the "Help" section, there are many threads about the lobby being down and what to do.
Templerun is only joinable from the lobby as I know of, which means that templerun is currently unavailable until the lobby comes back up. The rest of the minigames are available at the moment though.
Temple run is down cause the temple run is with /server lobby and /server lobby is down for now ItsHarry or ItsJerry will fix it cause mods can reload server so i think the Lobby will take time to be back
Minecraft sessions might be down. You can't connect to any server when that happens. But people who are in the server when sessions are down can still play, except when they leave the server. Ofc, they will be kicked out by the owners. :L
Minecraft sessions aren't down according to this: http://xpaw.ru/mcstatus/ It is most likely that the lobby is just down because I just joined using the buildit IP.
Temple run is on the same server as lobby, and it is down, so you can't access it. For other servers try anyone of those above.
