It wasn't just me... Finally talked to tech and as they were going through their script, signal came up. Apparently it was an issue at the uplink center, at least that is what the support person said. She said they were having an uplink issue with locals, but wanted to go through some checks anyway.. During that, the signal jumped back up.
Mpls/St.Paul locals for me. Though it sounded like it may have affected some others.
It caused some questions she asked to not be easy to answer... I.e was this affecting my locals on all my receivers... well, yes and no. The locals in HD on my 622 were fine, but those come in on 129.
