# Data Center Guide

Plain-English explanations of how data centers actually work. Power, cooling, redundancy, interconnection, and AI workloads.

## What is colocation

Colocation is renting space, power, cooling, and network in a data center while bringing your own servers. Customers buy rack units, a private cage, or a wholesale suite. Bitwrx provides the building; you bring the gear.

## Tier classification

Uptime Institute Tier ratings describe redundancy. Tier III is concurrently maintainable: any single component can be taken offline without affecting the IT load. Bitwrx operates Tier III facilities.

## Cooling and PUE

Power Usage Effectiveness measures total facility power divided by IT power. A perfect score is 1.0. Bitwrx YUL1 averages 1.18 thanks to free cooling and hydroelectric power. Higher-density AI racks use direct liquid cooling at YYZ2.

## Interconnection

Cross-connects link your equipment to carriers, cloud on-ramps, and other tenants. Bitwrx is carrier-neutral with 100+ carriers and seven cloud on-ramps on the platform fabric.
