Tuesday Night's PTAT Did Not Record

I have had PTAT turned on since I got my Hoppers (On on 1, Off on the other) and never had a problem. Tuesday night none of the shows recorded. I distinctly remember the yellow PT logo on the guide for all the shows but none of the shows were there. I looked to see if they got grouped incorrectly but that wasn't it either. I'm in NJ and wasn't aware of any type of outage. Nothing important was lost as most shows are in reruns but I haven't seen this happen yet.

Anyone else have this happen?

Actually, I meant to put this in the Hopper Zone so maybe one of the mods can move it. Thanks for the replies.
