France has suffered a new wave of deliberate sabotage targeting telecommunications infrastructure. The incidents occurred overnight on Sunday and disrupted fibre-optic networks across six regions.
Authorities confirmed installations belonging to major operators SFR and Bouygues Telecom were vandalised. Damage was reported in southern France, near the Luxembourg border and in areas around Paris, indicating a coordinated series of attacks on critical communications infrastructure.
Marina Ferrari, France’s Secretary of State for Digital Affairs, said: “Damage committed in several departments last night affected our telecommunications operators. I condemn these cowardly and irresponsible acts in the strongest possible terms.”
The full extent of the damage and the total number of customers affected remain under investigation. The deliberate targeting of fibre-optic cables suggests an intent to disrupt communications across multiple regions simultaneously, with potential effects on internet, fixed-line and mobile services.
According to Arcep, the French telecommunications regulator:
- The vandalism mainly impacted SFR’s fibre-optic network and also affected partner operators such as Free.
- Approximately 11,000 customers are believed to be affected, indicating the immediate consequences are significant but geographically limited.
- The attacks may have repercussions for both fixed and mobile networks, depending on the sites and routes damaged.
Arcep provides a public tool, “L’état des réseaux mobiles” (Mobile Network Status), to let citizens check the operational status of mobile sites in their area. The département of Meuse is reporting an unusual number of outages for one operator (Free), although investigators have not yet confirmed whether these are directly linked to the recent sabotage incidents.
Laure de La Raudière, President of Arcep, described the vandalism as “unacceptable and intolerable,” noting that networks and internet access are essential to daily life and are shared national assets. She extended her support to the teams working to restore services.
The timing of the attacks is particularly concerning, coinciding with France’s hosting of the Olympic Games. While Paris itself did not report major telecom disruptions related to these incidents, the events raise broader questions about threats to national security and the reliability of critical services during a period of intense international focus.
Law enforcement agencies have opened investigations to identify the perpetrators and determine whether the incidents are connected to other recent acts of sabotage. The geographically dispersed nature of the damage and the technical specificity of the targets suggest a level of planning and coordination that investigators will prioritize.
Security experts and industry leaders are urging increased investment in network resilience, rapid response capabilities and better coordination between the public and private sectors. These steps aim to reduce the impact of future attacks, speed repairs and strengthen protection around critical infrastructure.
The incidents underline vulnerabilities inherent in modern, interconnected societies and highlight how targeted physical attacks on communications infrastructure can cause significant disruption. Subsea cables and other hard-to-monitor components of the network have been singled out by analysts as especially sensitive and attractive targets for sabotage.
Government reports and defence assessments from several countries have warned of growing underwater and seabed activity by state and non-state actors that could threaten undersea communications infrastructure. Such analysis has prompted calls for enhanced monitoring and protection of cables, landing stations and related assets.
As restoration efforts continue, authorities are urging the public to remain vigilant and to report any suspicious behaviour near telecom facilities. Rapid reporting and coordinated response can help limit the duration and scope of outages.
Industry representatives emphasize that improving network redundancy, hardening physical sites and investing in rapid repair teams are essential steps to reduce the risk of widespread outages from similar attacks in the future.
