Tier 1 Adjacent™ is the site selection principle CleanArc uses to identify data center locations that offer Tier 1–grade connectivity without the constraints of fully saturated core markets. Grounded in network proximity, this approach positions sites close enough to major network hubs to deliver exceptional performance. In practical terms, CleanArc defines these locations as being typically within approximately two milliseconds round-trip latency of a major carrier hotel or internet exchange, supporting strong network access and long-term tenant optionality.

As digital infrastructure demands continue to evolve, being physically inside a Tier 1 market is not always the most scalable or effective solution; proximity to connectivity is what matters most. CleanArc’s Tier 1 Adjacent approach balances network performance and interconnection access with greater scalability, flexibility, and long-term planning potential. This strategy helps our sites avoid the constraints often associated with dense, overbuilt core markets while preserving the essential connectivity characteristics that hyperscalers and enterprises require.
