BBC Digital Radio stations down for some time yesterday (on DAB)

So yesterday, I was listening to the rather brilliant FA Cup coverage on Radio 5 Live on the DAB set. At one point, the coverage stopped and silence ensured. Other BBC stations seemed to be playing nothing (NO ENSEMBLE on my radio set). Non BBC stations seemed to be playing fine, and looking at Twitter at the time, it appeared it wasn’t just my radio set that was affected.

Just wondering what could cause this? It’s never happened before.
