Business Internet & Enterprise Connectivity in Sweden
Stockholm handles 55% of total Nordic internet traffic. The city runs on 35+ carriers, 125+ active network providers, and three of the major carrier-neutral data centres — Equinix (hosting Equinix IX, NetNod, and STHIX), Digital Realty (six-DC campus), and atNorth. AWS, Azure, and Oracle Cloud all have direct on-ramps there. In a region that's becoming a serious competitor to London and Frankfurt for data centre and AI infrastructure investment, Sweden is the centrepiece.
How we deliver in Sweden
We work with Telenor, Arelion, Tele2, Telia, and Colt across Sweden. Stockholm is our primary delivery city — enterprise DIA, Ethernet, and high-capacity wave services into the major data centre campus locations. For Nordic clients with requirements across \[Norway\](/countries/norway), \[Denmark\](/countries/denmark), and \[Finland\](/countries/finland), we manage the full Nordic footprint as a single regional programme. Lead time: 35 working days via Colt on-net in Stockholm.
Carriers, infrastructure and routing
Tele2 and Telia are the major enterprise carriers — Telia's network was rated best in Sweden by umlaut in 2025, with enterprise and public sector clients as a key focus. Telenor Sweden reached 3.09 million mobile subscribers in Q4 2025 and decommissioned all 2G/3G by late 2025, with 99.9% 4G/5G population coverage.
Colt deployed a new IQ Network route including dual Stockholm PoPs — up to 400Gb optical wave and 10Gb IP/Ethernet in the Swedish market. As Colt's number one global partner, we deliver into Stockholm's carrier-dense data centre ecosystem via that infrastructure.
Arelion (formerly Telia Carrier) is making significant 2025 investments in Scandinavian network infrastructure for hyperscale data centres and AI — upgrading to 1.6Tbps Waves and 400G coherent optics. Arelion's Falun campus PoP was upgraded to 400G/800G capability in Q3 2025. For high-capacity connectivity and financial services latency requirements, Arelion is our recommendation.
A note on cable security: the C-Lion1 cable (Helsinki-Rostock, passing near Sweden) suffered disruptions in November 2024 and February 2025, both suspected sabotage. The EU has allocated nearly €1 billion for subsea cable protection in the Baltic Sea region (€540M for digital infrastructure). This is live risk context that belongs in resilience planning for Nordic connectivity.

Sweden questions
Which carriers do you use in Sweden?
Telenor, Arelion, Tele2, Telia, and Colt. Arelion is our recommendation for high-capacity and financial services latency requirements; Colt for standard enterprise delivery.
How long does delivery take?
35 working days via Colt on-net in Stockholm.
What's the cable security situation in the Baltic?
C-Lion1 (Helsinki-Rostock) was disrupted twice in 2024-25, both suspected sabotage. The EU has committed €1B to Baltic subsea cable protection. Resilience planning for Nordic connectivity should account for this risk explicitly.
Can you manage Sweden with Norway, Denmark, and Finland as a single programme?
Yes — Nordic programmes are a standard engagement for us.
