Disruption of C-Lion1 Submarine Cable: Communication Connections Interrupted
State-owned data provider Cinia announced a fault in the C-Lion1 submarine cable. This fault has disrupted communication connections using the cable. Cinia is currently investigating the cause of this disruption.
Samuli Bergström from the Finnish National Cyber Security Center confirmed the break. He noted that disturbances can happen and may result from various factors such as weather or damage from shipping. He emphasized the importance of identifying the problems and taking corrective actions.
Bergström mentioned that Finland relies on several data connections to the rest of the world. Although one connection is currently down, the impact on everyday users is likely minimal.
The C-Lion1 cable stretches nearly 1,200 kilometers from Rostock, Germany, to Helsinki, Finland. It was commissioned in 2016 and is the only cable linking Finland to central Europe.
What impact does the C-Lion1 submarine cable fault have on internet connectivity in Finland?

News Directory 3: Mr. Bergström, thank you for joining us today. Can you provide us with the latest information on the C-Lion1 submarine cable fault announced by Cinia?
Samuli Bergström: Thank you for having me. Yes, Cinia has indeed reported a fault in the C-Lion1 submarine cable, which is a critical communication link between Finland and central Europe. This disruption is currently under investigation, and we are working closely with Cinia to determine the root cause.
News Directory 3: What are some potential causes for such a fault, based on your expertise?
Samuli Bergström: Disturbances in undersea cables can occur for various reasons. Common factors include extreme weather conditions, natural phenomena, or even physical damage caused by shipping activities. It’s essential to identify the specific cause to prevent future incidents.
News Directory 3: How significant is this disruption for data connectivity in Finland, given that the C-Lion1 cable is the only link to central Europe?
Samuli Bergström: While the C-Lion1 cable is indeed a vital link, Finland has multiple data connections to the rest of the world. Although the current fault may affect specific communication routes, the overall impact on everyday users should be minimal. Our redundancy measures and alternative connections help maintain service continuity.
News Directory 3: There have been reports of undersea cable damages in the region recently. How does this coincide with Finland and Sweden’s newfound security posture after joining NATO?
Samuli Bergström: Yes, the region has seen increased incidents of undersea cable damage, including recent issues affecting the Balticconnector gas pipeline and cables between Sweden and Estonia. While these situations raise concerns, it’s crucial to approach them objectively. Finland and Sweden’s NATO membership enhances our security and collaborative response, ensuring we are better prepared to address such challenges.
News Directory 3: What steps are being taken to ensure the resilience of our communication infrastructure moving forward?
Samuli Bergström: The investigation into the C-Lion1 cable fault is already underway, and part of that process will involve assessing our current infrastructure. We will explore options to enhance our resilience against potential threats and damages, such as better monitoring systems and alternative routing strategies. Continuous collaboration with international partners will also be critical in these efforts.
News Directory 3: Thank you, Mr. Bergström, for your insights on this critical issue. We appreciate your time and expertise.
Samuli Bergström: Thank you for having me. It’s important that the public stays informed about these developments.
In recent months, undersea cables in the region have experienced damage. In October 2023, Finnish authorities reported damage to the Balticconnector gas pipeline between Finland and Estonia, likely due to external activities. There have also been reports of damaged cables between Sweden and Estonia.
Both Finland and Sweden joined NATO after Russia’s invasion of Ukraine in February 2022, ending their long-standing neutrality.
