Selectel ltd: Berzarina Data Center

The Berzarina Data Center (Selectel, Moscow) is a flagship colocation campus located at 36 Ulitsa Berzarina, Building 3, Moscow, Russia. Operated and now fully owned by Selectel (after acquisition in 2022)it serves as one of Selectel’s largest and most strategic infrastructure hubs. The site’s central Moscow position gives it strong proximity to major business, financial, and administrative districts, permitting low-latency access to local networks, enterprises, government institutions, and metropolitan connectivity fabric.Control over the full building, including adjacent commercial real estate, gives Selectel maximal flexibility in expansion, engineering modifications, and integration of new systems. The facility is positioned as a high-reliability, carrier-neutral hub in the Moscow market, adding resilience to Selectel’s broader infrastructure footprint across its regions. 

⚙️ Facility Highlights

• Total power capacity of 11 MW delivered to the site, supporting full-load operations across its footprint. 
• Designed to house up to 1,500 server racks across its campus.
• Current server room footprint: ~ 2,777 m² with capacity for ~1,420 racks. 
• Full site area approximately 7,000 m² (gross built area). 
• Redundancy and reliability aligned with Tier III standards: redundant systems ensure service continuity even during maintenance windows. 
• Redundant power architecture (e.g. distributed-isolated 4/3N backup scheme cited in press) ensuring resilience against local utility outages. 
• Cooling systems: multiple redundant cooling loops (cold/hot aisles, precision air conditioning) in N+ cooling scheme. 
• Modular design enabling phased expansion, given that Selectel now controls the entire structure and adjacent parcels for future scaling. 

🔐 Security & Compliance

• 24/7 physical security with 100+ CCTV cameras covering entrances, perimeter, and interior zones. 
• Access control systems using magnetic cards, role-based access, multi-factor authentication, and security staff oversight. 
• Onsite staff and monitoring teams continuously manage infrastructure, environmental conditions, and threat response. 
• Compliance with Russian data and security regulations:
• • Compliance with 152-ФЗ (processing and storage of personal data) and related standards. 
• • Licensed under FSB / FSTEC for operations involving protected data systems (attestation under FSTEC orders No. 17 and 21) 
• • PCI DSS certification (for processing payment card data) in supported services. 
• Redundant monitoring and alarming across infrastructure layers to detect environmental anomalies, intrusion attempts, and infrastructure drift. 

🌐 Connectivity & Carrier Access

• Carrier-neutral facility: multiple network providers and backbone operators interconnect through the site. 
• Diverse fiber entry routes to avoid single points of failure; redundant fiber ducts and paths into the facility. (Selectel emphasizes diversity in network architecture) 
• Internal network architecture built with N+1 redundancy across network nodes to mitigate failure risk. 
• Regional interconnection: part of Selectel’s multi-data center mesh; cross-connects, metro dark fiber, and high-capacity links exist between this and other Selectel sites.
• Ability to peer or connect to Internet Exchanges and major transit carriers via on-site or adjacent infrastructure (common in Moscow colocation environment) — though specific IX names for Berzarina are not publicly disclosed.
• Full support for colocation, cross-connect, point-to-point links, and peering services via Selectel’s network platform. 

💼 Who It Serves

• Enterprises in financial services, e-commerce, banking, and fintech that require low-latency, reliable infrastructure in Moscow’s prime digital market.
• Telecommunications and network operators seeking a robust peering and interconnection hub in the Russian capital.
• Government agencies, public sector organizations, and regulated industry customers needing compliance with Russian data privacy and FSTEC/FSB standards.
• Service providers (cloud, SaaS, gaming, media) needing scalable, carrier-neutral colocation or hybrid infrastructure in Russia.
• Enterprises with legacy or mission-critical workloads that demand physical control, redundancy, and compliance assurances.
