Conapto Stockholm 1 City Data Center Sweden: 1MW Central Colocation & Recovery Hub
Status: Fully Operational Enterprise & Colocation Facility | Location: Sandhamnsgatan 63B, 115 28 Stockholm, Sweden
Project Overview
Conapto Stockholm 1 City is a strategically located urban colocation and workplace recovery data center situated at Sandhamnsgatan 63B in central Stockholm, Sweden. Designed to deliver approximately 1 MW of critical IT capacity, the facility spans around 1,300 square meters and features a dedicated computer room engineered to support enterprise colocation, hybrid cloud deployments, disaster recovery, and business continuity operations. Its central location places customers within minutes of Stockholm's primary financial and commercial districts, making it an ideal choice for organizations that require ultra-low-latency connectivity, rapid physical access to IT infrastructure, and secure workplace recovery facilities during business disruptions. The data center offers flexible colocation solutions ranging from individual server cabinets to fully enclosed caged suites, allowing enterprises to scale their infrastructure according to operational requirements. Engineered to high standards of reliability and security, the facility incorporates redundant electrical and cooling infrastructure, advanced environmental monitoring, EI-60 fire-rated compartmentation and fire protection systems, biometric access controls, secure mantrap entry points, 24/7 surveillance, and multi-layer physical security to safeguard mission-critical assets. Customers also benefit from direct fiber connectivity through multiple telecommunications providers, enabling resilient, carrier-neutral network access and low-latency connections to cloud platforms, internet exchanges, and enterprise networks across Sweden and Europe. Sustainability is a core aspect of the facility's operation, with electricity sourced from 100% renewable energy through Vattenfall's 24/7 energy matching program, helping organizations reduce the environmental impact of their digital infrastructure. Combining resilient colocation services, premium security, flexible deployment options, renewable energy sourcing, and a prime central Stockholm location, Conapto Stockholm 1 City provides a highly reliable and future-ready digital infrastructure platform for enterprises, financial institutions, government agencies, and technology providers.
