Inside the Westland Bunker: What Tier III Actually Means

·6 min read

Our offices are inside the Westland Bunker. Our team works out of it every day. Our colocation clients have hardware there. When we write 'Tier III data center' on the website, people sometimes ask what that actually means. Short answer: it's a specific set of engineering and operational standards, not a marketing claim.

The Uptime Institute tier classification

The tier system comes from the Uptime Institute and rates data centers on redundancy and maintainability. Tiers run from I (basic) to IV (fault tolerant). Tier III is the most common rating for serious commercial data centers.

What Tier III means specifically

  • Redundant power and cooling paths (N+1 at minimum)
  • Concurrently maintainable — you can service any piece of infrastructure without taking the facility offline
  • 99.982% availability target (about 1.6 hours of downtime per year)
  • Multiple independent utility paths
  • On-site backup power (diesel generators with fuel contracts)
  • Climate control that's itself redundant

Why this matters to a Houston business

Houston has hurricanes, ice storms, grid instability, and occasional heat events that stress power infrastructure. A Tier III facility is engineered to keep running through all of that. During Harvey, during the February 2021 freeze, during any of the more routine ERCOT grid stress events — a real Tier III facility stays up.

Why we chose to work inside one instead of just selling cloud

Because we support clients in compliance-heavy industries where physical controls matter, and because we wanted our engineers to have direct access to client hardware rather than pass-through remote-hands tickets. The operational difference is real.

We're not the operator of the Westland Bunker — it's independently run. We're a tenant. But we're a tenant who's in the building every day, which is not something most MSPs can say about any data center, anywhere.
