Some 124,000 homes in parts of Staffordshire Shropshire, Cheshire, Black Country, Herefordshire and Worcestershire were affected.
Engineers are investigating the cause of the loss of transmission.
In a phone call to the BBC, someone claiming to represent Fathers 4 Justice said they had interrupted the service.
But this morning the leader of Fathers 4 Justice, Matt O'Connor, told the BBC he was not aware of the action and that it had not been sanctioned by them.
He said: "I would be very unhappy if it was one of our members. We have a strategy and this doesn't fit in with our strategy."
A spokesman for West Mercia Police confirmed an investigation had begun and that damage to equipment had been located and the cost was being assessed.
