Tier Advisor
Map your data center's power, cooling, network, and site infrastructure to Uptime Institute Tier I-IV, TIA-942 Ratings 1-4, and EN 50600 Availability Classes — with regional compliance overlays for 12+ jurisdictions.
What is Tier Classification?
The Uptime Institute Tier Standard classifies data centers from Tier I (basic, 99.67% availability) to Tier IV (fault tolerant, 99.995% availability) based on infrastructure topology and redundancy. TIA-942-B uses "Rated" levels 1-4 with additional telecom and security requirements. EN 50600 defines Availability Classes VK1-VK4 aligned with European standards.
This calculator maps your actual infrastructure against all four major frameworks simultaneously, identifies which subsystem limits your classification, and shows exactly what upgrades are needed to reach the next level.
