For commercial real estate investors, few asset classes are accelerating like data centers. The surge of AI, cloud, and high-density compute has turned land with power access into the new digital gold rush.
But while the market (and media) focus almost exclusively on power availability, there’s a second, equally critical element that determines the long-term success and valuation of any data center development:
Connectivity. Fiber. Network reach.
Without it, even the most power-rich site can underperform—or fail entirely.
Why Power Isn’t the Whole Story
It’s true: securing the right amount of power can make or break a data center project. Substations, long-lead utility timelines, and escalating MW demands dominate headlines for good reason.
But power is only the first half of the equation. The other half is how the facility connects to:
- Major internet exchanges (IXs)
- Cloud on-ramps
- Carrier hotels
- AI clusters and hyperscale ecosystems
- Global networks
If the data center can’t move data with low latency and high redundancy, it simply can’t attract top-tier tenants—or command premium valuations.
Fiber Determines the True Value of the Site
1. Network Diversity = Tenant Confidence
Hyperscalers and enterprise customers demand a minimum number of diverse fiber paths, plus proof those paths don’t share underground risk points. No diversity = no deal.
2. Latency Drives AI & Cloud Workloads
The fastest-growing workloads—AI training, inference, HPC—depend on proximity to fiber routes and IXs that minimize latency. A site 10 miles from the wrong fiber line could perform dramatically worse than one sitting on a well-connected route.
3. Carrier Accessibility Impacts Long-Term ROI
You can add power.
You can build cooling.
But you can’t easily reverse-engineer new long-haul fiber routes. Carrier presence can expand, but only if the economics make sense—and that takes time. Investors with the foresight to analyze fiber early gain a compounding competitive advantage.
4. Network Design Impacts Construction Timelines
Today’s biggest project delays aren’t always utilities—they’re permitting and building new fiber laterals, validating routes, and coordinating multiple carriers. Early network engineering shaves months off delivery timelines.
The Hidden Risk in Many “Power-Rich” CRE Sites
Many land parcels being pitched as “data center ready” are evaluated solely for substations, MW availability, and land zoning—but not fiber viability.
This leads to common (and costly) surprises:
- Discovering the nearest carrier line is lit but not diverse
- Finding out the “three carriers nearby” actually share a single duct
- Learning that long-haul routes lack capacity for AI traffic
- Delays caused by municipalities unfamiliar with fiber construction
- Having to redesign the site due to a missed fiber easement
Smart investors look beyond the power map and into the digital foundation beneath the soil.
What Savvy CRE Investors Are Doing Differently
The most successful data center investors now conduct dual-front due diligence:
1. Power Feasibility Analysis
(As expected)
2. Network & Fiber Infrastructure Assessment
(Where many competitors fall behind)
This includes:
- Fiber route mapping
- Carrier diversity verification
- Latency analysis to key IXs and cloud on-ramps
- Backbone and dark fiber availability
- Construction feasibility for laterals
- Redundancy planning for long-term scaling
By incorporating both, investors position their projects for better tenant fit, stronger underwriting, and faster lease-up.
The Bottom Line: Power Gets You to the Starting Line. Fiber Gets You Across the Finish Line.
For CRE investors entering or expanding in the data center market, the opportunity is enormous—but so is the competition. Sites that combine power plus intelligent network design will stand apart and attract the most valuable tenants.
Power drives operations.
Connectivity drives revenue.
Ignoring fiber isn’t just an oversight—it’s a risk to your investment strategy.
