The problem on the network of France's biggest telecoms provider Orange first hit at 11:37 a.m. on Monday and lasted until 8:30 p.m., with outages of up to nine hours for some customers, Orange France CEO Jérôme Hénique told Le Figaro, according to the South China Morning Post (SCMP) — at the core of the outage was a software bug in Nokia's code, new to Orange and “extremely complicated to find”.
