When I visited China 2 years ago, I stayed in a hotel for a few days which had BBC Worldwide. Given that I spend most of the time there in student accommodation, it was quite comforting to finally have UK news!
Interestingly, Liu Xiaobo (Nobel Peace Prize from China who was very vocal about democracy in China) died on the day I arrived at my hotel. The news had a section about this which went on for 15-20 seconds until the screen went completely blank. The other channels were working fine, but the BBC news channel wasn't working at all. 5 minutes later, it switched back on again halfway through another news feature.
I obviously can't confirm it, but I am convinced it was shut off to censor the information. It seems too much of a coincidence.
