Undersea cables cut: Baltic tensions resurface

  • GlobalConnect has confirmed it is addressing a network outage in Finland caused by damage to two separate internet cables, while assuring that no undersea cables have been affected
  • GlobalConnect and Cinia initiate repair efforts amid geopolitical concerns in the Baltic Sea region

What happened: Cable outages, Finland-Sweden connectivity

Finnish cable company Global Connect announced its services were disrupted as a result of two cable breaks on an internet line between Sweden and Finland. “Major outage in Finland caused by separate incidents in our network, no sea cables are affected,” the company first reported Monday (December 2) evening.

This latest disruption comes two weeks after an incident involving two undersea fiberoptic communication cables in the Baltic Sea — one between Finland and Germany and another between Sweden and Lithuania — where breaches sparked suspicions of sabotage.

The cables, critical for internet and communication services, are undergoing repairs, although adverse weather conditions may delay progress. Finnish authorities and GlobalConnect are closely investigating the cause of the damage while working on temporary rerouting to minimize service interruptions. The incidents occurred following warnings about potential hybrid warfare tactics targeting European infrastructure​.

What it’s important

The disruption of undersea cables in the Baltic Sea highlights vulnerabilities in global communication infrastructure and has tangible impacts on small businesses. For example, Finnish tech startup XYZ Cloud Services (a pseudonym for illustrative purposes) relies heavily on seamless data transfers through international networks to serve clients across Sweden and Germany. With outages delaying critical cloud-based operations, such companies face client dissatisfaction, financial losses, and strained resources to implement temporary workarounds. These challenges disproportionately impact small firms that lack the capital reserves of larger corporations to absorb such disruptions.

Similar incidents in the past, such as the accidental cable cuts in Southeast Asia in 2022, caused major slowdowns for local internet providers and businesses, demonstrating the global significance of these infrastructures. In the Baltic region, geopolitical tensions exacerbate the risks, with hybrid warfare tactics increasingly targeting civilian and commercial systems.
