Techopedia Explains Tier 1 Data Center

A Tier 1 data center is the basic-intermediate level of data center tiers.

Introduced by the Uptime Institute, it is used to provide neutral classification of data centers, in terms of availability. A Tier 1 data center only has essential components or data center infrastructure and is not suited for enterprise or mission critical data center services, as it lacks any redundant source of servers, network/Internet links, storage, power and cooling resources.

Typically, a Tier 1 data center guarantees 99.671 percent availability and has an average of 28.8 hours of downtime per year.
