Chinese-owned TikTok said in a statement that its second “billion-euro data centre” in Finland would be located in Lahti in the country’s south, forming “part of our continued expansion of secure digital infrastructure in Europe” to strengthen “long-term commitment to the country”.

Christian Hannibal, head of public policy for TikTok in Finland, said the Nordic country “offers a unique combination of strong digital infrastructure, access to clean and reliable energy, and a highly skilled workforce”.

Due to its suitable conditions, several major data centre investments have been made in Finland in previous years, including by technology giants Microsoft and Google.

“Once operational, the Lahti data centre will strengthen our ability to support the default storage of European user data in Europe, under strict access controls and advanced monitoring systems,” TikTok said in a statement.

The video-sharing platform has, meanwhile, faced accusations of addicting users to content, as several countries plan limitations on social media use for minors.

In February, based on the preliminary conclusions of a probe opened two years earlier, the European Commission said it found TikTok was not taking effective steps to address the app’s negative impacts, especially on minors and vulnerable adults.

TikTok announced its first data centre in Finland, located in Kouvola, in May 2025, calling it a “significant step” in its commitment to data security in Europe.

The announcement then sparked a political debate around the company’s transparency and data security.
