There have been issues with the SD national LDL and squeezeback. Just before the LDL cued out a few minutes ago, it was frozen at the CC for Philadelphia (or was it Pittsbugh?), with a white box over the icon. After that, when the squeezeback was supposed to cue, everything was black except for the program and an ad. Once the LDL cued back in, it was stuck for a few seconds with the logo fading in. There are white boxes over all the icons on the LDL.
Also, a few years ago before the HD relaunch
, there was a map with airport delays, and on it, all airports were listed as closed.
