It does not look like INS has stopped adjudication completely. In my case, they issued RFE on 11/22. I still don't have the details. I heard it on AVM. Online status has not been updated. It still says 420 to 450 days. Doesn't even mention FP dates.
My details are: RD 8/23/2001
ND 9/26/2002
FP 7/31/2002
