I HATE to be the one to bear bad news, but the server is down again. There was a HUGE lag spike at 3AM, just when we were about to leave anyway, but we HAD to leave, it was insufferable. Chunks wouldn't load and you couldn't break any blocks or pick stuff up because it lagged out. But when we left, it was still running just SUPER laggy, now this morning it's down, we can't connect. Sorry for bearing the news Matt, but if you could get it fixed ASAP that would be great c:. Also, as you know I know more than enough about servers, plugins and the like and other stuff, so I can help you out if you need it man.
Either way, let me know if I can be of help, if not then good luck getting it back up, I think you may just have to check the server log and find out what was done/placed/change at the time of the lag, because something caused it, it went from running really well to unplayable.
Let me know bro, Jack (JKT667)
