TikTok is set to invest €1 billion (approximately $1.16 billion) in constructing a second data centre in Lahti, southern Finland, aiming to bolster its strategy of storing European user data locally. This initiative is part of a larger €12 billion European data sovereignty program that aims to protect the data of over 200 million users. The new facility will start with a capacity of 50 megawatts (MW), expandable to 128 MW. Finland has become a preferred location for data centres due to its cold climate and affordable, carbon-neutral energy sources. However, the investment has stirred political concerns, particularly regarding transparency and national security, as highlighted by former Economic Affairs Minister Wille Rydman. TikTok's existing data management practices involve rigorous security protocols across facilities in Norway, Ireland, and the United States, with its first Finnish hub in Kouvola expected to be operational later this year. Meanwhile, TikTok is also experiencing leadership changes, with the departure of advertising lead Khartoon Weiss, following a trend of high-profile exits from the company.
