A preliminary investigation was opened on Wednesday after a wave of malicious acts of unprecedented scale targeting the national fiber optic network, said the Paris prosecutor's office.

The cyber section of this prosecutor's office has opened an investigation on the grounds of "damage to property likely to harm the fundamental interests of the Nation", "obstructing an automated data processing system" and "criminal association", concerning these incidents that led to slowdowns and cuts in internet access in several major French cities on Wednesday, including Grenoble, Besançon, Reims and Strasbourg.
