Data centers are ordinarily described as facilities that host computing, storage, networking,
and digital-service equipment. That description is technically correct, but increasingly incomplete.
Modern data centers support financial transactions, healthcare systems, government services,
communications, transportation, artificial intelligence, scientific research, industrial operations,
defense activities, and global supply chains. They are no longer merely buildings containing servers.
They have become concentrated ecosystems upon which many essential services depend.
The United States currently organizes critical infrastructure through sixteen federally recognized sectors,
including Information Technology, Communications, Energy, Financial Services, Healthcare and Public Health,
Transportation Systems, and Government Facilities. Data centers are generally treated within the Information
Technology Sector rather than as an independent sector. That administrative placement may be appropriate,
but it does not resolve the more important analytical question.
Have data centers become sufficiently essential, concentrated, interconnected, and difficult to replace
that they should be evaluated as a distinct critical infrastructure, critical subsector, or cross-sector
critical enabling infrastructure?
This commentary does not propose that every server room, commercial hosting facility, or privately operated
computing site should be declared critical infrastructure. Rather, it argues that large-scale data-center
ecosystems should be subjected to a formal criticality test.
Data Centers as an Ecosystem
A modern data-center ecosystem includes much more than computing equipment. It depends upon continuous
electrical power, backup generation and fuel, cooling and heat-rejection systems, water or other cooling
resources, fiber and telecommunications routes, cloud and identity-management platforms, semiconductors
and specialized accelerators, software and firmware supply chains, physical and personnel security,
trained operators and contractors, maintenance and restoration capabilities, and legal, regulatory,
and governance structures.
At the same time, the data center may support hundreds or thousands of downstream organizations.
A single facility, provider region, identity plane, or network conduit can therefore become a common
point of dependency across otherwise unrelated institutions.
Critical infrastructure supports data centers. Data centers support critical infrastructure.
Energy systems, communications networks, water services, transportation, finance, and specialized supply
chains enable data-center operation. In return, data centers host the digital services, operational platforms,
records, applications, analytics, and communications upon which those same sectors increasingly depend.
The Data-Center Infrastructure Ecosystem
The relevant analytical object is not the building alone. It is the
Data-Center Infrastructure
Ecosystem (DCIE)
: the combined physical, digital, industrial, human, supply-chain, governance,
and restoration environment through which nationally consequential computing services are delivered and recovered.
The ecosystem contains facilities and computing assets; legitimate compute, storage, identity, control-plane,
backup, and recovery functions; network relations; power and cooling systems; operators, engineers, vendors,
and contractors; mission and restoration requirements; ownership and accountability structures; energy, water,
communications, semiconductor, software, transportation, finance, workforce, and supply-chain dependencies;
geographic and environmental conditions; and service-level, recovery, backup-autonomy, maintenance, and lifecycle timing.
Figure 7. Data-center infrastructure ecosystem as a cross-sector critical enabling infrastructure candidate.
The diagram separates essential services, VOSFIT context, physical and digital dependencies, state and control
measures, and the governance path from an Information Technology Sector asset to a Systemically Important Entity
or candidate subsector or sector. Select the figure to open the full-size depiction.
A representative data-center state should therefore measure more than ordinary uptime. Relevant state variables
include service availability; general-compute, accelerator, storage, and network capacity; latency; reliability;
data and control integrity; primary-power adequacy; backup autonomy; cooling and thermal margin; water or other
cooling-resource sufficiency; human and restoration readiness; and governance assurance.

Mission dependence
Dependent essential functions, workload criticality, service obligations, and consequence of interruption.
Mission tiering, workload ownership, continuity agreements, and restoration priority.
RTO/RPO, clean-restore time, spares, staff availability, exercises, accountable authorities, and unresolved findings.
Immutable backups, golden images, spare pools, mutual aid, restoration exercises, named accountability, enforcement, and corrective-action tracking.
Interpretive conclusion: Data-center infrastructure is a present cross-sector Critical Enabling
Infrastructure candidate. Individual facilities and provider ecosystems may already satisfy substantive
critical-infrastructure or Systemically Important Entity criteria. Independent subsector or sector treatment
remains conditional on demonstrated mission consequence, timely substitutes, governance gaps, boundary coherence,
and the measurable benefit of designation.
Criticality Is Not Determined by Size Alone
A large data center is not necessarily critical merely because it consumes significant power or contains expensive
equipment. Likewise, a comparatively small facility may be critical if it hosts an irreplaceable government,
healthcare, defense, emergency-response, or financial function. Criticality must therefore be evaluated through
mission consequence rather than physical scale alone.
Under the VOSFIT-CI theoretical approach, the relevant questions include:
What essential functions does the facility or provider ecosystem support?
Which sectors and missions depend upon it?
What would happen if the service became unavailable, corrupted, manipulated, or inaccessible?
Are substitute facilities genuinely available?
Can workloads be moved within the required restoration period?
Are identity, networking, backup, and control systems truly independent?
Are dependencies geographically or institutionally concentrated?
Who is accountable for continuity, restoration, and public consequence?
The distinction between nominal redundancy and effective substitutability is particularly important.
Two contractual providers do not constitute meaningful resilience when both depend on the same power region,
fiber conduit, identity provider, software platform, semiconductor source, or management plane.
The VOSFIT Perspective
The VOSFIT Model represents advanced persistent and hybrid threats through:
Θ = (V, O, S, F, I, T)
In this formulation, vulnerabilities, origins, strategies, functions, intentions, and time are analyzed as a
structured and evolving system. Applied to data centers, the vulnerability dimension extends beyond software flaws.
It may include common power or cooling dependencies, inadequate backup autonomy, shared telecommunications routes,
concentrated cloud-control planes, physical-security weaknesses, insider access, maintenance deficiencies, untested
restoration procedures, supply-chain concentration, governance fragmentation, corruption, procurement manipulation,
false certification, competence deficiencies, staffing shortages, and accountability failures.
Potential origins may include criminal organizations, hostile states, terrorists, insiders, compromised suppliers,
accidental failures, environmental events, or unresolved causes. Strategies may involve cyber intrusion, physical
sabotage, credential abuse, supply-chain compromise, capacity exhaustion, deception, alarm suppression, data
manipulation, or interference with restoration. The resulting functions may include disruption, concealment,
persistence, propagation, manipulation, exfiltration, capacity degradation, or delayed recovery.
Data-center risk cannot be reduced to cybersecurity alone. A facility may remain uncompromised
from a conventional network-security perspective while still becoming unavailable because of power failure,
cooling loss, fuel disruption, water constraint, contractor failure, institutional negligence, or shared regional dependency.
Should Data Centers Become a Seventeenth Sector?
The evidence does not yet require a categorical answer. Three governance options should be considered:
Remain within the Information Technology Sector, but with stronger and more explicit treatment of data-center
dependencies, continuity, concentration, restoration, and cross-sector effects.
Create a defined data-center subsector or critical-enabling-infrastructure designation, allowing more focused
governance without establishing an entirely new federal sector.
Consider independent sector treatment if future analysis demonstrates that data centers possess sufficiently
distinct functions, vulnerabilities, restoration requirements, dependencies, and governance gaps that existing
sector structures cannot adequately manage them.
The correct decision should not be based on terminology, industry influence, or technological enthusiasm.
It should be based on measurable dependency, consequence, substitutability, restoration difficulty, concentration,
and governance effectiveness.
Conclusion
Data centers have become too consequential to remain analytically invisible inside a broad Information Technology
category. They may not yet require immediate designation as a separate federal critical-infrastructure sector.
Nevertheless, they should be evaluated as a cross-sector critical enabling infrastructure whose disruption could
affect multiple nationally essential functions simultaneously.
The broader lesson is equally important: critical infrastructure cannot remain a permanently fixed list.
National dependency evolves. Technologies mature. New ecosystems emerge. Systems that were once optional become indispensable.
What infrastructure is officially designated as critical?
What has become critical, even though existing classifications have not yet fully recognized it?
That is precisely the type of question the VOSFIT Model is intended to examine.
