evidence: On April 27, an unknown individual or group deliberately cut crucial long-distance internet cables across multiple sites near Paris, plunging thousands of people into a connectivity blackout. The vandalism was one of the most significant internet infrastructure attacks in France’s history and highlights the vulnerability of key communications technologies. Now, months after the attacks took place, French internet companies and telecom experts familiar with the incidents say the damage was more wide-ranging than initially reported and extra security measures are needed to prevent future attacks. In total, around 10 internet and infrastructure companies—from ISPs to cable owners—were impacted by the attacks, telecom insiders say. The assault against the internet started during the early hours of April 27. "The people knew what they were doing," says Michel Combot, the managing director of the French Telecoms Federation, which is made up of more than a dozen internet companies. In the space of around two hours, cables were surgically cut and damaged in three locations around the French capital city—to the north, south, and east—including near Disneyland Paris.
