A Tier 1 data centre represents the entry-level classification in the Uptime Institute’s tier system. It offers basic infrastructure with minimal components and no redundancy for power or cooling systems. Tier 1 facilities are suitable for small businesses with non-critical IT needs and provide a 99.671% uptime guarantee, translating to about 28.8 hours of downtime annually. They are affordable but lack resilience, and any equipment failure can lead to service disruption. These facilities often serve as starting points for businesses with limited budgets or low operational risks.
