Dauphin Telecom

Dauphin Telecom, also known simply as Dauphin Telecom, is a telecommunications company headquartered in France. The firm provides voice and data connectivity services that support both regional and international communications. Its operations include the management of submarine transport infrastructure that links the French Antilles with North America. By maintaining this undersea cable, the company enables reliable transmission of traffic between the Caribbean islands and the continental United States and Canada. Dauphin Telecom serves customers ranging from individual consumers to business enterprises that require cross‑border connectivity. The company's positioning in the market is defined by its focus on submarine‑based links that complement terrestrial networks.

On April 8, 2023, Dauphin Telecom suffered a significant network disruption when a distributed denial‑of‑service attack targeted the submarine transport cable connecting the French Antilles to North America. The malicious traffic overwhelmed the cable’s capacity, causing a loss of service for users relying on that link. In response, the company's technical teams deployed reinforced security solutions designed to mitigate the attack and protect data integrity. These measures included traffic filtering, rate limiting, and additional monitoring capabilities. As a result of the implemented defenses, normal operations were restored by the end of the following Monday. The incident highlighted the importance of robust DDoS protection for critical submarine communications infrastructure.
