Between December 28 and December 30, 2025, several breaks occurred on undersea internet cables connecting Sweden and Estonia. Estonian authorities reported five cable breaks in total, with three attributed to storm conditions and at least two incidents considered suspicious. The damage affected key routes of Estonia's internet backbone, putting the country's connectivity at risk of significant disruption. Swedish authorities acknowledge one cable damaged but have not disclosed detailed information, while cause remains officially 'likely storm' but is treated skeptically by Swedish officials. Analysis suggests some confusion in cable identification, with multiple breaks on what may be the same cable. Investigation is ongoing with unclear timelines and cable identities. The event highlights vulnerabilities in critical infrastructure and potential for covert sabotage attempts.
