The American company opened a server hall in Luleå in 2013 – its first ever data centre outside the US – then later built a second nearby in 2014.

The planned hall would be 380 metres long and cover 31,000 square metres. The application will be examined by the local building and environment council on Tuesday, and administration officials have proposed that the permit should be granted.
