All of mine came back today, except one, Le Cellier! So I just called and confirmed, and it is still there, yay!
There is also a message saying that the dining reservation system will be upgrading on 11/16 so you will not be able to make ADR's that day, and the system should be back to normal on 11/17. I'll be there during that time, so I hope it doesn't mess anything up!
