  • Tier 2: A Tier 2 data centre has certain redundant and backup components in addition to a single path for power and cooling. The anticipated uptime is 99.741%. (22 hours of downtime annually).
  • Tier 3: A Tier 3 data centre is prepared with various channels for power and cooling. As well as upgradable and maintainable systems that may be used without putting the facility offline. The anticipated uptime is 99.982%. (1.6 hours of downtime annually).
  • Tier 4: A Tier 4 data centre includes redundancy for every component and is entirely fault-resistant. It should remain online 99.995% of the time (26.3 minutes of downtime annually).
