Government

Critical infrastructure

Reliability architecture

Zero downtime

Ability to service any node (power, cooling, UPS) without stopping client servers. Concurrent Maintainability.

N+1 redundancy

Every critical system component has a duplicate ready for instant activation. Power is supplied via two independent routes.

Energy independence

Two independent power feeds and dedicated diesel generator units with fuel reserves for dozens of hours of autonomous operation.

Physical security

Multi-level access control system, 24/7 video surveillance, and automatic gas fire suppression.

Carrier-grade connectivity

The data center serves as a point of presence (PoP) for major backbone operators. Communication channels are physically redundant via diverse routes.

Engineering systems monitoring

DCIM system tracks thousands of sensors in real time. A 24/7 duty shift responds to any deviations from normal parameters.
