How many regions have a second gallery? The problem also might not have been in the gallery.

A few of the larger sites have a presentation gallery for smaller bulletins, the Project England spec used a Quartz vision mixer but outside of a separate mixer, the sources were all from the existing infrastructure into the main gallery, so assuming the issue was in the apps for that particular region then either way they'd be still be stuffed.

ISTR that NWT is produced from a smaller, separate studio/gallery during breakfast that is independent of the main gallery so there's some resilience.
