I have noticed that on wsaz channel 3 in my area for the past few months. It happens for a few minutes, I change channel and all the other local
channels are fine. There is no announcement or apology for disruption, when it comes back on they go on like nothing happened.
out here in stockton calif. i've noticed MSNBC doing the same thing...going to just a dark grey screen and earlier today it happened on ABC.... and i
have comcast...combine that with CERN being shut down and the HUBBLE telescope shut down...coincidence???
