Ouch!! No, everything seems to be fine and I was watching till 11pm. All my OTA are coming in very well. I'm in South Natomas and have been having no trouble at all. Check your connections.
Mine came back around 10:30. I'm in a bit of a valley in Rockliln, and am awaiting an antenna upgrade, so I suppose it was my signal, but it just shocked me that they were all gone! I regularly lose a couple, but this was the first time for all!
