About SE1 Atlas Stockholm

SE1 Atlas Stockholm is a data center operated by Kolo and located in Stockholm, Sweden. Kolo presents the facility as one of its two interconnected Stockholm metro sites, publicly describing SE1 Atlas and SE2 Tellus as a twin-site setup with built-in geographic redundancy. SE1 is positioned in Stockholm’s established industrial district, with direct access to the E4/E20 corridor and proximity to major commercial activity around Kungens Kurva, while remaining within the broader Stockholm metro economy, one of the Nordic region’s most important business and digital hubs.

Kolo positions SE1 Atlas for enterprise, AI, and hybrid deployments that require low-latency metro access, resilient infrastructure, and Swedish sovereign hosting. The facility is also notable for its integration with Stockholm’s district heating ecosystem: Kolo states that SE1 recovers excess heat and feeds it into the city’s district heating network, aligning the site with energy-efficiency and heat-reuse objectives in one of Europe’s most mature urban heating markets.

⚙️ Facility Highlights

  1. Part of Kolo’s Stockholm twin-site platform, with SE2 Tellus located 10 km away for geographic redundancy.
  2. Combined power capacity across Kolo’s Stockholm facilities is publicly stated as 6 MW.
  3. True N+N power distribution with independent A+B power paths to each cabinet.
  4. Backup systems are described as N+N and Tier 3 equivalent.
  5. Powered by 100% certified Swedish renewable energy backed by Guarantees of Origin.
  6. Hot/cold aisle containment with N+1 redundant cooling units.
  7. Supports high-density deployments of up to 50 kW per cabinet, with higher densities available on request.
  8. Free cooling is operational for approximately 40% annually, using Sweden’s climate conditions.
  9. Closed-loop cooling systems use low-GWP refrigerants.
  10. Waste heat recovery systems feed energy into Stockholm’s district heating grid.
  11. On-site solar panels contribute to the renewable energy supply.
  12. Colocation configurations scale from a single cabinet to private suites.
  13. On-site migration and setup support is available.
  14. On-site support is available during business hours, with 24/7 on-call availability and 24/7 Remote Hands service.

🔐 Security & Compliance

  1. SSF Protection Class 3 facility.
  2. 24/7/365 security guard presence.
  3. Multi-factor authentication access control.
  4. Double interlocked door systems at entry points.
  5. Client-specific security enhancements are available on request, including EMP protection.
  6. Fire detection is based on a VESDA early warning system.
  7. Fire suppression includes zoned Inergen and Novec gas suppression.
  8. Secure customer environments include private suites and controlled cabinet-level deployments.
  9. The facility is in Sweden, so hosted environments operate within an EU jurisdiction where GDPR is relevant. This is a jurisdictional inference, not a claimed certification.

🌐 Connectivity & Carrier Access

  1. Designed as a Stockholm metro-edge facility for low-latency enterprise and AI workloads.
  2. Interconnected with SE2 Tellus as a twin-site Stockholm ecosystem.
  3. Positioned close to major Stockholm transport and business corridors, including direct E4/E20 access.
  4. Suitable for hybrid deployments; Kolo’s platform messaging includes private links to AWS, Azure, Google Cloud, and sovereign clouds, though this is described at platform level rather than as an SE1-only cross-connect list.
  5. Suitable for enterprises, AI workloads, SaaS platforms, and hybrid infrastructure requiring metro proximity and geographic redundancy across Stockholm. This is an inference from Kolo’s SE1 positioning and service model.

💼 Who It Serves

  1. Enterprises requiring sovereign colocation in Stockholm.
  2. Organizations deploying AI and HPC workloads needing high-density rack capacity.
  3. Businesses requiring hybrid deployments with private infrastructure control.
  4. Customers needing single-cabinet through private-suite colocation footprints.
  5. Organizations implementing dual-site resilience across the Stockholm metro.
