Data centre downtime: Utility infrastructure dependencies

As published in the Urban Developer (opens a new window).

Property owners and investors are betting big on data centres, but utility and infrastructure risks could quietly erode the success of these projects if left unaddressed.

As data centres continue their transformation from a niche asset class to institutional investor favourite, the conversation has rightly shifted from hype to fundamentals. Including uptime, energy efficiency, and long-term resilience.

But while much attention is paid to cybersecurity and energy sourcing, another critical risk is often hiding in plain sight: the infrastructure that keeps a data centre running is rarely fully within your control.

From shared utility corridors to offsite substations and fibre exchanges, these dependencies introduce a web of operational, legal and insurability challenges that can catch even seasoned developers off guard.

Invisible but critical: what infrastructure risks really look like

Most data centre stakeholders are across the need for dual power feeds.

But fewer understand that both power feeds might travel through the same conduit, across the same easement, or be supplied via a single point-of-failure substation kilometres away.

Scenario example:

A developer commissions a Tier III facility with dual power feeds.

On paper, the system is resilient. But a major civil works project severs the underground conduit that carries both feeds along a shared route.

Result: complete outage, and a lengthy insurance negotiation.

Why insurers are paying close attention

Insurers are increasingly scrutinising not just what’s on site, but how and from where critical services are delivered.

We’re seeing greater focus on:

  • Single points of failure in offsite electricity, water or cooling infrastructure

  • Uninsurable third-party infrastructure with unclear ownership or maintenance regimes

  • Inadequate documentation or mapping of critical utility routes

This scrutiny affects insurability, pricing, and the ability to secure adequate business interruption (BI) coverage.

If there’s uncertainty around infrastructure resilience, some insurers will:

  • Apply exclusions or sub-limits for BI triggered by utility failure

  • Decline cover altogether for certain high-risk sites

  • Require independent infrastructure resilience assessments

Beyond insurance: valuation risks

It’s not just about insurability. Hidden infrastructure risks can impact the success and longevity of a data centre project.

  • Exit hurdles: Investors undertaking due diligence may flag utility dependencies as red flags

  • Tenant hesitancy: Hyperscalers and enterprise tenants increasingly request resilience audits, SLAs with utility providers, and redundancy certifications

  • Cost creep: Retrofitting true route separation or infrastructure upgrades mid-project can be materially expensive

What leading developers are doing differently

Sophisticated property groups are embedding infrastructure risk assessments early in site selection and design processes, such as:

  • Independent utility route audits

  • Negotiating custom SLAs with offsite utility providers

  • Designing in physical and geographical separation for power and fibre

  • Engaging with insurers during design to validate insurability

The next frontier of data centre risk management

As competition in the data centre space intensifies, the difference between a Tier III facility on paper and a truly resilient asset comes down to the infrastructure.

Property owners and developers who proactively address offsite utility risks are often better placed to secure tenants, insurance, and long-term value.

At Lockton, we work closely with developers, investors, and insurers to identify and help manage the full spectrum of risks, both visible and hidden, across the data centre lifecycle.
