Damaged Undersea Cables Disrupt Communications Between Finland, Germany, Sweden, and Lithuania
Underwater communication cables between Finland and Germany, as well as Sweden and Lithuania, have been damaged, reported cable operators on Monday.
The Finnish company “Cinia” stated that an underwater communication cable connecting Finland and Germany is compromised. The reason for the damage is still being investigated, raising concerns in both the Finnish and German Foreign Ministries.
All telecommunications using the “C-Lion1” underwater cable have been disrupted, confirmed by Cinia, which builds fiber optic networks and provides telecommunications services. Samuli Bergström, the communications manager at Finland’s National Cyber Security Centre “Traficom,” announced that an investigation into the cable damage has commenced. He explained that disturbances can occur due to various factors, including weather or shipping activities.
Traficom confirmed that Finland’s international communication links are affected by the cable damage. However, Finland has multiple data connections, and residents may not notice the disruption in their daily lives.
Cinia reported the damage was identified late Sunday night. The cause of the damage remains unknown.
Additionally, a communication cable connecting Sweden and Lithuania was found damaged on Sunday. The telecommunications company “Telia” confirmed that the “Arelion” cable, linking Gotland and Lithuania, is physically damaged. However, Telia’s customers in Lithuania have not experienced significant disruptions.
How do underwater cables contribute to national security and what measures are in place to protect them?
News Directory 3 Exclusive Interview: Unraveling the Underwater Cable Damage Crisis
By [Your Name], Editor
In light of the recent reports regarding the disruption of underwater communication cables between Finland and Germany, as well as Sweden and Lithuania, we sought expert insight to understand the implications of this incident. We spoke with Dr. Anja Lindholm, a specialist in telecommunications infrastructure and cybersecurity at the University of Helsinki, to gain a clearer picture of the situation.
News Directory 3: Thank you for taking the time to speak with us, Dr. Lindholm. Can you explain the immediate impact of the damage to the “C-Lion1” underwater cable on telecommunications between Finland and Germany?
Dr. Lindholm: Certainly. The “C-Lion1” cable is a critical piece of infrastructure for telecommunications, as it facilitates a significant volume of data traffic between Finland and Germany, and beyond. The disruption of this cable means that services like internet access, data transfer, and telecommunications have been severely impacted. This can affect businesses, individual users, and even governmental communications.
News Directory 3: What are the potential causes of damage to underwater cables, and how are investigations typically conducted?
Dr. Lindholm: Underwater cables can be damaged by a variety of factors, including fishing activities, ship anchors, environmental conditions, and even natural disasters. In this case, since no definitive cause has been established yet, it is crucial that the investigation focuses on gathering evidence from both maritime traffic reports and potential environmental factors in the affected area. Teams often deploy remotely operated vehicles (ROVs) to inspect the cables and determine the extent of the damage.
News Directory 3: With both Finnish and German Foreign Ministries raising concerns, what does this incident say about the importance of these cables to national security?
Dr. Lindholm: This incident highlights the vulnerability of critical communication infrastructure and its potential implications for national security. Disruptions like these can expose nations to increased risk if they are heavily reliant on this technology for secure communications, especially during sensitive times. Ensuring the integrity and security of these cables is vital for maintaining not just commercial telecommunications but also defense-related communications.
News Directory 3: Moving forward, what measures should be taken to prevent similar incidents in the future?
Dr. Lindholm: It’s essential to enhance monitoring and protective measures for underwater cables. This could include improved tracking of shipping lanes and an increase in awareness regarding the locations of these communications lines among maritime operators. Additionally, collaborating internationally to create a standardized response framework for handling such incidents can help mitigate their impact.
News Directory 3: Thank you, Dr. Lindholm, for your invaluable insights into this pressing issue. As we continue to follow this developing story, it is evident that the integrity of our communication infrastructure is of utmost importance.
Dr. Lindholm: Thank you for having me. It’s crucial that we remain vigilant and proactive in ensuring the resilience of our telecommunications systems.
Stay tuned to News Directory 3 for further updates on this incident and its ongoing investigation.
The “C-Lion1” cable spans 1,173 kilometers, connecting Finland’s Santahamina Island to Rostock, Germany. Completed in 2016, it is Finland’s only underwater cable directly linking it to Central Europe.
According to the portal “Verkkouutiset,” the “C-Lion1” cable features eight pairs of optical fibers with a transmission capacity of 144 terabits per second. When inaugurated, Cinia noted that data center operators “Hetzner Online,” “TeliaSonera,” and the Russian telecommunications operator “Avelacom” planned to connect this cable to their networks extending from Finland to Moscow.
In October 2023, an electricity cable and gas pipeline between Finland and Estonia were damaged. An investigation suggested that an anchor from a Chinese ship caused the damage. Around the same time, Sweden reported separate damage to a cable connecting it to Estonia.
In January of the previous year, authorities indicated that damage to another electricity cable between Finland and Estonia was likely not caused by an external factor.
Meanwhile, the 2022 rupture of the “Nord Stream” gas pipeline between Sweden and Denmark remains unresolved.
