The BBC World Service English service has reportedly been blocked in China with all shortwave transmissions being jammed by what the broadcaster is called 'extensive and co-ordinated efforts'.
While it's not possible to determine exactly where the source of the jamming is coming from the BBC believes that an operation on this scale is 'indicative of a well-resourced country such as China.'
If true this would be a major step back for a country which had only just started to relax its grip on the country's internet services and communications networks.
In a statement the BBC said it 'Strongly condemns this action which is designed to disrupt audiences' free access to news and information.' adding that 'the deliberate and co-ordinated efforts by authorities in countries such as China and Iran illustrate the significance and importance of the role the BBC undertakes to provide the impartial and accurate information to audiences around the world.'
This isn't the first time the BBC has come under attack from governments with Iran jamming BBC Persian whilst the BBC World Service was jammed significantly during the Cold War.
