Myths and misconceptions of tier certification
Uptime Institute’s Tier Classification System for data centers has reached the two-decade mark. Since its creation in the mid-1990s, Tiers has evolved from a shared industry terminology into the global standard for third-party validation of data center critical infrastructure. In that time, the industry has changed, and Tiers has evolved with it, remaining as relevant and important as it was when Uptime Institute first developed and disseminated Tiers. At the same time, Uptime Institute has observed that public understanding of Tiers has been clouded by the many myths and misconceptions that have developed over the years.
