I can confirm that the first set of escalators are all back in action... didn't venture to the lower lot on my last visit so I didn't bother to pay attention to them. However, in an interesting bit of news... THEY REVERSED THE DIRECTION OF THE ESCALATORS!!!
The two on left are now the "DOWN" escalators, the 2 on the right are now the "UP" escalators. Not sure if this change is permanent or not, but it was definitely weird.
