From posts in the South and South East thread in the Newsroom is sounds like a quite complex failure.
With the previous programme's credits failing I wonder if the failure was in pres, when they tried to do the ECP
? The observation that all was ok in Wales and NI and only momentarily screwed up in Scotland suggests that the clean feed to the nations was fine.
Apparently Southampton failed to opt, I wonder if they missed the cue in and amongst the likely chaos on talkback while pres tried to get things back?
Write that down in your copybook now.
