Not the real money one, this is a normal gold AH.

For some weird reason, the auction house is being very fickle. When I search for weapons and armour, it gives me a completely empty auction house. Sometimes it does work, sometimes it doesn't.

I've found a topic on the Diablo forums saying the AH is bugged. Sometimes it just can't access the database and it shows it as empty. I'm on north america by the way.

I guess that answers the question

I think you're right indeed. Just now the list appeared once then it's gone again >_<
