We're currently working with our host to fix some issues with the servers. We will update you when we have anymore information. Right now, we don't have an ETA, but we're hoping it won't be too long.
Thank you for your patience.
UPDATE: Just Survival is offline right now, we are working on some chunk loading/saving issues that are causing the server to crash. I will update again soon~
UPDATE2: Survival is back online! Sorry for the delay, we are hoping these corrupted chunk issues are fixed now :)
