Google said on Monday it would invest another 450 million euros ($607 million) over the next few years on a data center in southeastern Finland, a boost for a country struggling with Nokias decline and weakness in paper and steel industries. The investment is in addition to 350 million euros the worlds No. 1 Internet search company has already spent on the data centre, built on the site of paper company Stora Ensos former mill in Hamina, Finland. Google bought the mill in 2009, turning it into one of its most efficient data centers by taking advantage of the Bay of Finlands naturally chilly seawater to cool its servers.
