It seems they are back live now on both channels. On the NC it seems they have lost furio track datas for the cameras but for WN the cameras seems to operate normally.
I'm pretty sure that Global comes from Studio B (or whichever one they normally use for Newsnight and Victoria), which are manually operated by humans (afaik?) and not controlled by a computer, thus they'll work as normal.
EDIT: Was confirmed earlier by another poster.
