Best-In-Class Infrastructure Since 2002

About Us

We began in the quiet after one boom,
and built for the next.

Sentinel was founded in 2002, when most of the industry was fleeing the dot-com crash and we saw the foundation of something lasting. That patience is now a $6B+ development pipeline trusted by some of the world’s most demanding hyperscale and enterprise customers. We’re a data center developer and operator, but our real product is certainty: secure, uninterrupted power, cooling, and connectivity for the applications your business can’t afford to fail.

Why Sentinel

Substance
Over Form

Our 20+ year track record of delivering both enterprise and hyperscale facilities for the most stringent customers in the industry speaks for itself. We don’t cut corners. We pursue excellence in every detail. And we build custom, build-to-suit data centers shaped around the way each customer actually operates, not the other way around.

Designed by premier engineers to the highest quality and resiliency standards and operated by highly-trained, diligent and experienced technicians.

Flexibility to accommodate the individual nuances of each customer’s program, and optimized for flexible growth and densification over time.
