Infrastructure Tiers

We divide our infrastructure components into 3 tiers:

• Tier 0: Critical: These are mission critical infrastructure components. If these become unavailable or have significant disruption, it will have a major impact.

• Tier 1: Essential: These components are important, but not as critical as tier 0. They are part of our core operations, but if they become unavailable the impact is important, but not major.

• Tier 2: Non-Essential: These are auxiliary components. Their unavailability does not have a major impact.
