Thanks for the patience everyone. There was one RAM module, it was replaced so we shouldn't have those random all server down times.
We're TF2 guys. We don't use MS time, we use Valve Time: https://developer.valvesoftware.com/wiki/Accurate_Valve_Time#Reverse_Valve_Time
How do I actually join the server? When I try to go to in through my Minecraft Multiplayer, I enter this - Server Name: JustinGuy - Server Address: smp7.empireminecraft.com. When I click Done, it says "Can't Resolve Hostname. Am I doing something wrong? Please Help. Thank You.
Try smp7.empire.us. For some reason when I had it as the one you use it kept doing that. empire.us works for me.
No, that is a Craftbukkit ++ issue and was NOT fixed with the server reboot. To answer the imminent questions, I have no idea when the mob problem will be fixed. It all depends on if we are to downgrade Craftbukkit or wait for an update.
