I logged in this morning, and could see immediately that we had a problem, and reported it to yuku as soon as I saw it.
Most of the yuku boards that run on the server we rely on had the same issues, and it wasn't just our board alone.
I apologize for the trouble, and will try to find out more details of what happened.
The latest update is that it should be back to normal at this point.
Thanks for understanding and hanging in there while it was resolved....
