The Uptime Institute has released the latest update of the Tier Standard: Topology”，于 2018 年 1 月 1 日生效。This 2018 update to the Standard specification (previous update was dated 2012) is the result of more than five additional years of real-world data center experience and additional application notes associated with the use of newer technologies found in many recent data centers. The 2018 update to the Tier Standard : Topology reflects the experience drawn from organizations completing Uptime Institute’s Tier certification and additional experience gathered by Uptime Institute Professional Services during the conduct of its professional services portfolio. Mostly clarification to eliminate any ambiguity as well as providing additional context in nature, the 2018 update to the Tier Standard : Topology clarifies the intent of Uptime Institute regarding a number of topics, including; the need for on-site power generation, definitive ambient temperature ranges, a recommendation on communications entries, and makeup water for evaporative cooling systems.
Uptime Institute Tier Standard：Operational Sustainability 是客观的方法，可帮助数据中心业主根据所安装的机房基础设施的适用 Tier 开展设施管理项目，从而实现组织的业务目标或任务要求。Tier Standard：Operational Sustainability 确定了除 Tier Classification 系统（I、II、III 和 IV）外、可能长期影响数据中心性能的行为和风险。Tier Standard：Operational Sustainability 有助于确保机房管理行为符合相应机房基础设施的 Tier 功能。
Accredited Tier Designer 技术论文系列进一步阐明了特定子系统的 Tier 影响，是数据中心机房基础设施“Tier Standard：Topology”的补充。Tier 计划的目标之一是，确保设施系统应用一致的基础设施可用性概念，从而支持数据中心关键环境。

Uptime Institute’s Tier Topology standard has been created to assure any organization can meet its required levels of business services by relying on a predictable level of performance in the data center. While power is one of the most critical resources used to operate any data center, the types of power utilized to operate that data center greatly influence the results achieved. With 20 years of incident data across more than 1000 data centers to draw from, the Uptime Institute Tier Standard asserts that onsite power generation is the only source of reliable power. The high level of performance available from Tier certified datacenters stems from power distribution designs that rely only on this reliable power.
