An investigation is under way after a cyber attack at Virgin Media Television.
The broadcaster said the company had been affected by an "unauthorised attempt" to access its systems in recent days.
It said broadcasting of some of its recorded programming on Virgin Media 3, 4, More and VMTV Player will be affected.
Minister of State Ossian Smyth the matter was being investigated by the National Cyber Security Centre.
In a statement earlier, Virgin Media Television said it operates stringent cyber protection measures and said it uses precautions which it immediately activates in such instances.
It said some technologies would be temporarily disconnected to ensure maximum security while it complete a review process.
It said it expects normal service will be resumed as soon as it has completed the review and verification process.
The broadcaster said the issue relates to Virgin Media Television only and does not relate to any other Virgin Media Ireland operations.
