Ofcom's crackdown of BT and Openreach continues. The UK regulator has dealt the pair a £42 million fine for late broadband installations fitted on behalf of rival internet service providers, such as Sky and Virgin Media. Openreach handles the bulk of Britain's broadband infrastructure -- so to keep the market fair, it's legally obliged to set up new lines within 30 working days. Inevitably, Openreach encounters problems and occasionally can't meet that deadline. In exceptional circumstances, it can assume a contract extension by the ISP and reduce the compensation it would normally have to pay. However, Ofcom found that BT did this "retrospectively over a sustained period" to avoid fines. Tut-tut.
