On 17-18 November 2024, two submarine telecommunication cables, the BCS East-West Interlink and C-Lion1 fibre-optic cables were disrupted in the Baltic Sea. The incidents involving both cables occurred in close proximity of each other and near-simultaneously which prompted accusations from European government officials and NATO member states of hybrid warfare and sabotage as the cause of the damage. Currently, the damage to those undersea cables has not been conclusively attributed to any specific party. Investigations are ongoing and since 19 November, the Chinese cargo ship Yi Peng 3 is under scrutiny due to its presence near the cables at the time of the incidents. Western intelligence officials believe the ship's anchor may have caused the damage, either accidentally or under the influence of Russian intelligence.

On 25 December 2024 at 12:26 EET, the Estlink 2 had an unplanned failure, reducing the Estonia–Finland cross-border capacity from 1,016 MW to 358 MW. Fingrid expects the failure to last until August 2025. At the time of the outage, electricity was flowing from Finland to Estonia at a rate of 658 MW. Concerns about potential sabotage rose due to recent outages in the Baltic Sea region, although subsea cables are also prone to technical malfunctions and accidents. Finnish Prime Minister Petteri Orpo confirmed that authorities were investigating the incident.
