> Google will build new data centres in Kajaani, Muhos and Vaala

Wow, these are really far north. I checked on Google Maps: They are all about as far north as Oulu. It must get incredibly cold during the winter. Wiki tells me the region is at or below freezing for about six to seven months per year! I am curious how much cheaper is cooling in these locations compared to more temperate climates in continental Europe.
