Data Center Tours: Questions to Ask on‑Site

A facility tour is one of the most important steps in selecting a colocation provider. This guide provides a detailed checklist of what to look for and questions to ask during your visit. We cover physical security observations (entrance procedures, escort requirements, surveillance coverage), infrastructure inspection (power systems, cooling equipment, generator testing schedules), and operational assessment (staff expertise, monitoring capabilities, ticket response times). Learn how to evaluate the quality of existing customer installations, what red flags to watch for, and how to assess whether the facility truly matches the tier rating and certifications claimed. The guide includes questions about everything from network carrier availability to fire suppression systems, helping you conduct a thorough evaluation that goes beyond glossy marketing materials.
