Years ago transmitters regularly used to have periods of being off-air or reduced power, but now they're rarely interrupted. Thimgs are much more reliable and need less maintaining.
The nearest you get to a channel going off air are the overnight tests on BBC Radio. But even there it's only for a few minutes and only on one platform.
A lot of work takes place all the time - things go wrong, things are replaced, tested etc but it's not something you'd notice on air. Switching is designed, and generally is seamless
