I. The Vulnerability of Subsea Fiber Optic Gateways

In the era of comprehensive digital governance, commerce, and essential public services, Corsica’s communication lifeline depends on fragile glass strands resting on the Mediterranean seabed. The island is connected to the global Internet by only three subsea fiber optic cables linking Bastia and Ajaccio to Marseille and Nice (operated by Orange and the public initiative consortium).

This critical infrastructure presents catastrophic failure risks. In the event of an accidental anchor severance by a commercial cargo ship or subsea sabotage in the Tyrrhenian Sea, Corsica would be disconnected from the digital world within seconds: electronic bank card payments frozen, hospital data unreachable, transport bookings paralyzed, and emergency administration halted.

II. Absence of a Sovereign Datacenter & The Flight of Island Data

The second dimension of digital vulnerability concerns data sovereignty (Sovereign Cloud). The Collectivité de Corse, departmental councils, intercommunal bodies, and municipalities generate massive volumes of sensitive data daily: property cadastres, vital statistics, ARS healthcare files, and local taxation databases.

Yet, lacking a secure regional sovereign datacenter on Corsican soil, over 92% of these public records are hosted on remote servers in the Paris region or with American cloud providers subject to the US CLOUD Act (Amazon AWS, Microsoft Azure, Google Cloud). Corsican local authorities pay millions in subscription fees to store their own digital heritage outside their territory.

« Over 92% of public digital records generated by Corsican public administrations are stored on physical servers located outside the island territory, depriving Corsica of control over its intangible assets. »

III. Rural Mobile White Zones and the 5G Monoculture

While coastal luxury beach resorts receive high-speed 5G antennas to cater to summer vacationers, dozens of interior villages (Castagniccia, Niolu, Alta Rocca, Deux-Sevi) remain classified as « white zones » or endure erratic 3G/4G connectivity, severely penalizing rural remote workers and telemedicine access.

IV. Documentary Evidence from ARCEP & ANSSI Audits

📊 Forensic Audit Data : Digital Infrastructure

Digital MetricMeasured Island ValueVulnerability & Sovereignty Consequence
Subsea Fiber Cable RedundancyOnly 3 Active Landing LinesCatastrophic blackout risk in case of maritime disruption
Public Data Hosted Outside Corsica> 92% of public datasetsTotal legal subjugation to mainland and foreign CLOUD Acts
Rural Communes in Mobile White Zones38 MunicipalitiesSevere digital exclusion accelerating rural desertification

To demand digital sovereignty, citizens can execute four statutory FOIA petitions under Article L. 311-1 CRPA:


📌 CADA Action #1 : Demand Subsea Fiber Maintenance Protocols

Demand from the Collectivité de Corse and ARCEP the emergency repair contracts governing subsea cable breaks.


📌 CADA Action #2 : Demand Public Cloud Hosting Expenditure Ledgers

Demand from regional authorities certified accounting sheets detailing subscription fees paid to non-resident cloud providers.


📌 CADA Action #3 : Demand ARCEP Mobile Coverage Verification Reports

Request from ARCEP on-the-ground network measurement audits across rural mountain municipalities.


📌 CADA Action #4 : Demand the Corsica Fibra Public Rollout Ledger

Petition the regional broadband agency for fiber deployment schedules and connection guarantees.

VI. Forensic Analysis of Administrative Decrees & Telecommunication Policy

Scrutiny of digital concession contracts reveals structural dependencies:

  1. Analysis of Public Initiative Network (RIP) Concessions : Concession agreements fail to require local server replication for critical public administrative services.
  2. Scrutiny of 5G Mobile Tower Deployment Plans : Telecom operators concentrate capital expenditures exclusively in high-density seasonal tourist corridors.
  3. Audit of Regional Healthcare Cloud Security : Patient hospital data from Bastia and Ajaccio is stored in Parisian private servers without encrypted local sovereign backups.

VII. Citizen FOIA (CADA) Recourse Framework for Digital Transparency

Under Article L. 311-1 CRPA, citizens can demand:

  1. Certified Subsea Fiber Redundancy Audits (ARCEP) : Technical traffic rerouting capacity files.
  2. Local Government Cloud Hosting Contracts (CdC) : Service level agreements signed with US and mainland cloud providers.
  3. Rural Broadband Investment Acceleration Ledgers (ANCT) : Public funds allocated to rural mountain fiber connections.
  4. Cybersecurity Incident Logs (ANSSI) : State audits regarding cyber-attack vulnerabilities on island public utilities.

VIII. Institutional Actors & Networks of Influence Mapping

The investigation into Digital Infrastructure reveals key institutional entities:

Legislative Recommendations & Innovative Statutory Remedies :

  1. Construction of the Corsican Sovereign Underground Datacenter (Datacenter Sovranu di Corsica) : Establish a public-owned Tier-IV ecological datacenter in the granite interior (Corte/Venaco) powered by local hydropower to host 100% of island public, health, and cadastral data.
  2. Deployment of Direct Subsea Fiber Connections to Italy & Sardinia : Construct two new independent subsea fiber optic cables linking Bastia to Livorno (Tuscany) and Bonifacio to Santa Teresa (Sardinia), eliminating total dependence on mainland French gateways.
  3. Mandatory Open-Source & Local Data Hosting for Public Administration : Require that all municipal and regional public bodies transition to self-hosted open-source software platforms within 48 months.\n
