I don't understand what the Arctic circle has to do with this. It's a data centre, not an HPC cluster. Data centres don't run nearly as hot as clusters.

All data centres have cooling. They get cooling for free 7 months of the year!

  So it really is about the cooling. Ok, thanks.

I saw a small data center (4 racks) get from 18C to 55C in one hour when the chillers failed. And that was the air temperature, not the server temperature. In theory you can just open the doors, but then you cannot control the humidity.

I do also have a problem understanding what the Arctic Circle has to do with this. North of arctic circle in America and Scandinavia is two totally different things

  Ok, I'll bite. What do you mean?

    The Nordic countries have a rather mild climate despite being so far north. To have a comparable temperature in the Americas, you'd usually need to be a couple of thousand kilometers further south. (E.g. I guess the climates of Boston and Stockholm might be roughly comparable, but Boston is actually on the same latitude as Rome). So if you tell an American that something is almost at the Arctic circle, their intuition will tell them it's a very rough and almost uninhabited place. You tell it to a Finn, and they'll think that it's where the fourth largest metropolitan area of the country is, or where you go for a comfortable ski holiday.

    I have lived north of the circle for most of my life, and the feeling I have is that 13 C in October and having winters where it is more days with around 0 C than -15C is not what most peoples associate with north of the arctic circle. The difference is that we have warm water coming with the Gulf Stream creating a completely different climate compared to other places north of the circle.

Did you read the article? Have you ever been in a data center?
