The reliability of CSC data center is extremely high. There are several power and communication lines as well as excellent fault tolerance available. Due to the stable operations and excessive renewable power sources available, the probability of power failures is very low. As one token of our reliability and commitment, CSC holds the ISO 27001 certificate as one of the first data centers in Finland.


The CSC data center is perfectly suited for modular expansion. The existing infrastructure has been built for heavy industry use, and it can be scaled for specific customer needs.


Kajaani is the only supercomputing site in the Nordics, that supports seamless MD-VPN integration for flexible international connectivity. Excellent connectivity is available to all cloud providers, including major commercial ones such as Google, Microsoft, Amazon, Akamai, Facebook, Apple etc., through the NORDUnet global peering infrastructure. The Ethernet/InfiniBand switch infrastructure provides over 100 Tbit/s of aggregate bandwidth.

Strong regional ecosystem

The Kajaani region is on its way to become an Arctic data hub, thanks to the growing data center ecosystem. The data center industry has become one of Kajaani’s strengths, engaging numerous ICT companies. In addition, local authorities, universities, funding organisations, and industry are all onboard in the ecosystem. The planned Arctic data cable will bring even more added value to this development.
