I have to admit, in all my years of DXing and using an antenna, I've never seen this before - a broadcaster actually trying to explain to viewers why they may not be receiving a station's signal.

There won't be anything at the link below most here don't know, but it's unusual to see an over-the-air broadcaster trying to tell regular viewers what it's all about. And they offer a service to track the issues along a host of media - from TV to DAB (which is common over there) to AM, FM, and LW. 

You can see the BBC's explanation to viewers about sudden reception loss here.
