GridColo Reliability Tiers
GridColo Reliability Tiers classify facility design intent, redundancy posture, maintainability profile, operational controls, and site-specific SLA commitments. They are separate from Powered by GridColo program tiers. Final tier designation and SLA terms are documented in the applicable service agreement.

Understanding Reliability Tiers
GridColo Reliability Tiers ensure transparency and consistency across facilities. Each tier describes a target level of infrastructure redundancy, redundancy posture, and site-specific service commitments — not a universal specification applied identically to every site.
Where a customer, market, lender, insurer, or agreement requires third-party validation, GridColo can support site-specific assessment, documentation, and audit processes. Final reliability classification and SLA terms are documented in the applicable service agreement.
