The problem got resolved some time in the night and I brought the game itself back up this morning.
I don't have all the specifics on what happened yet. One part of what happened is that the virtual machine that the game runs on was transferred from one physical machine to another which required a shutdown of the virtual machine. Anyone one connected to the game at the time may have gotten the message "Going down, be back in a bit!"
Anytime you receive that message it may be because a MUCK staffer initiated a shutdown of the game OR it is because the machine the game runs on is shutting down.
Unfortunately, after the move, something else went wrong, _possibly_ due to a power failure in the data center in which the physical machine resides. If there's more news, I'll add it as a comment to this news story.
Feaelin.
