I am a regular viewer of this channel as it gives a good overview of all Asian news, while watching the news at 10.00pm last night they mentioned the headline about the no confidence motion in Thai govt and also a demonstration occuring outside parliment when all of a sudden the telecast was stopped with a slide saying technical problems ?? I did not have my VPN activated then but this morning with VPN activated I watched the whole telecast on this issue. Was this just a coincidence or censorship ??? 

It's censorship, and regularly happens to the BBC in Thailand also when they broadcast about politically sensitive topics.
