Business Internet & Enterprise Connectivity in Finland

Finland's data centres are in the middle of a sustainability story that's changing how enterprises think about where to put compute in Europe. Waste heat from Helsinki data centres feeds the city's district heating network. Power comes from nuclear and renewables. Equinix alone operates seven Helsinki facilities (HE1-HE7). The C-Lion1 cable — the only direct submarine link between Helsinki and Rostock, Germany — suffered suspected sabotage disruptions in November 2024 and February 2025. Cable resilience is not an abstract consideration in Finland. It's recent news.

How we deliver in Finland

We work with DNA, Elisa, Telia Finland, and Colt across Finland. Helsinki is our primary delivery hub. For Nordic programmes combining Finland with \[Sweden\](/countries/sweden), \[Norway\](/countries/norway), and \[Denmark\](/countries/denmark), we manage the full footprint as a single engagement. Lead time: 35 working days via Colt on-net in Helsinki.

Carriers, infrastructure and routing

DNA is Finland's second-largest mobile operator and first in fixed broadband subscriptions — accelerating its cloud transformation with a plan to migrate 80% of enterprise applications to public cloud by 2030, and strengthening its backbone terrestrial connections to Sweden. Elisa is expanding fibre to 200 new locations in 2025, with AI-driven autonomous network operations via Google Cloud partnership. Telia Finland remains a significant enterprise carrier despite internal restructuring and price increases from July 2025.

Colt provides UCaaS, SD-WAN, and SASE capabilities to Finnish enterprises, with global network reach connecting Finnish data centres and business hubs into Colt's wider European infrastructure. As Colt's number one global partner, we deliver via that network with consistent SLAs and pre-validated engineering.

Helsinki has 25+ carriers and carrier-neutral facilities including Equinix HE1-HE7, GlobalConnect, and Hetzner. Most facilities provide direct cloud on-ramps. A new submarine cable connecting Sweden and Finland via the Åland Islands is scheduled for completion by end 2026 (GlobalConnect), adding capacity and redundancy. Eastern Light Sweden-Finland I and II are expected in 2027.

The C-Lion1 disruptions are relevant context: the cable was cut in November 2024 and again in February 2025, both events suspected to be deliberate. Finland's international cable resilience planning now explicitly includes this threat model — and enterprise buyers should too.

Finland questions

Which carriers do you use in Finland?

DNA, Elisa, Telia Finland, and Colt. Selection depends on location and service type.

What happened with the C-Lion1 cable?

Finland's direct submarine link to Germany suffered suspected sabotage disruptions in November 2024 and February 2025. Traffic rerouted via alternative paths but with latency impact. Resilience planning for Finnish connectivity should account for single-cable risk.

Are there cloud on-ramps in Helsinki?

Yes — most major Helsinki data centres provide direct cloud on-ramps to AWS, Azure, and other major providers.

How long does delivery take?

35 working days via Colt on-net in Helsinki.
