At the end of an unmarked path on a tiny island at the edge of Stockholm’s extensive Baltic Sea archipelago lies an inconspicuous little wooden cabin, painted a deep shade of red. Water gently laps the snow-dusted rocks, and the smell of pine fills the air.
The site offers few clues to the geopolitical drama that has gripped Scandinavia in recent months, driven by accusations of infrastructure sabotage. But in fact the cabin houses a key cog in Europe’s digital connectivity, and a point of vulnerability in a potential hybrid war: a datacentre that amplifies the signal from a 1,615-mile fibre-optic cable running from northern Sweden to Berlin.
