The BBC has confirmed that its digital services are not working in its most popular TV channel, BBC One, following a number of problems in recent weeks.
The network has reported that it has been forced to delay some of its most important programmes, including Sherlock, which had been due to air on Tuesday.
It also confirmed that the network was to air a second series of The X Factor, the reality competition show that has been plagued by technical issues in recent months.
The X-Factor has also been delayed in a number other countries.
However, there has been no official word on whether BBC One will also be forced to pull the plug on The Great British Bake Off.
