Data Center: Critical Digital Infrastructure Under Threat

Global data centers are becoming the "heart" of the digital economy, yet they are also increasingly exposed to multiple threats. From cyberattacks targeting IT systems, to physical strikes in military conflicts, to community protests triggered by resource consumption, these critical facilities underpinning cloud computing and AI computing power are facing unprecedented strategic-level risks. The German Federal Bank reported that its IT systems come under more than 5,000 cyberattacks per minute; in a recent Middle East conflict, Iran's drone and rocket attacks on Amazon AWS data centers brought physical strikes into the data center security agenda. Data centers, the foundation of modern digital civilization, have quietly become the focus of a new round of security competition.

Event Overview

According to public information, there are currently about 12,000 data centers globally, of which the Frankfurt region has 76, making it one of the most important data center hubs in the region. DE-CIX Frankfurt is a leading global internet exchange point, with peak traffic exceeding 17 Tbps, equivalent to nearly 3.5 million people watching HD video simultaneously. With the explosive growth of AI applications, demand for data center construction has risen sharply; for the Dietzenbach project alone, Google plans to invest billions of dollars.

However, the security situation of these facilities is far from reassuring. In March 2021, a large data center in Strasbourg, France, caught fire, taking more than 3.6 million websites offline, and some customers permanently lost data because backup storage was located in the same building. In January 2026, the German Federal Bank announced that its IT systems face more than 5,000 cyberattacks per minute. In April of the same year, the Maine legislature voted to impose a moratorium on data centers exceeding 20 megawatts, reflecting serious public concerns over resource consumption.

Technology and Risk Analysis

The risks facing data centers can be divided into three categories:

• Cyberattacks: including DDoS, intrusion, ransomware, etc., aimed at stealing data or disrupting services.
• Physical attacks: In the Russia-Ukraine war and Middle East conflicts, IT infrastructure has been directly listed as a strike target. Iran launched drone and rocket attacks on AWS facilities in Bahrain and the UAE, causing severe disruptions to banking and payment systems; Iran subsequently published a list of 30 potential targets.
• Accidents: such as fires, power outages, etc. The Strasbourg incident shows that physical damage can be equally devastating.

From the perspective of the attack chain, cyberattacks can penetrate through internet entry points, supply chains, insiders, and other vectors; physical attacks directly destroy facilities. For cloud service providers, once a data center is paralyzed, the impact can spread along the dependency chain to critical industries such as finance, transportation, and energy.

Affected assets include: servers, storage systems, network equipment, cooling systems, power supplies, and the various cloud services and online applications that rely on these facilities.

Enterprise Impact Analysis

• For enterprises, the consequences of data center security incidents are direct and severe:- Operational Risk: Service interruptions bring business to a standstill. The Strasbourg incident once made millions of websites inaccessible, and enterprises relying on cloud services face similar predicaments.
• Financial Risk: Direct and indirect losses from downtime can be enormous; in addition, data center construction itself faces community opposition and regulatory hurdles. For example, the Gross-Gerau project was shelved after the local council rejected it, causing huge investor losses.
• Compliance Risk: Data centers designated as critical infrastructure must meet higher security and availability standards, requiring enterprises to invest more in compliance building.
• Brand Risk: Service interruptions can weaken customer trust, especially in sensitive industries such as banking and healthcare.
• Data Risk: Data loss is difficult to recover, especially when backups and primary data are located at the same physical site—a sobering lesson.

Industry Trend Observations

Data center security is no longer a purely IT issue; it has risen to a national strategic agenda. In March 2026, the German government issued a national data center strategy, planning to double Germany's data center capacity by 2030 and reduce dependence on non-European providers. This shows that data centers are becoming a new frontier in geopolitical competition.

At the same time, the explosive growth of AI has intensified data center resource demands and amplified their environmental controversies. From Chile to Maine in the United States, protests and policy restrictions are reshaping data center siting logic. In the long run, data centers need to strike a balance among efficiency, security, and social acceptance.

This is not an isolated incident but an emerging major trend: the security of critical digital infrastructure is extending from cybersecurity to physical security, supply chain security, and geopolitical security.

Defense and Response Recommendations

In response to the above risks, we recommend that enterprises build a defense system at the following levels:

Enterprise Level:

• Geographic redundancy: Deploy critical operations across multiple geographic regions to avoid a single data center becoming a point of failure.
• Data backup: Ensure backups are stored in different geographic locations to avoid a repeat of the "same-building backup" tragedy.

Technical Level:

• Strengthen cybersecurity: Deploy EDR/XDR, SIEM, and zero-trust architecture, and continuously monitor for abnormal activity.
• Physical security: Collaborate with professional physical security teams, including video surveillance, intrusion detection, and personnel access control.
• Attack surface management: Regularly assess the exposure of network and physical assets.

Management Level:

• Threat intelligence: Share threat intelligence with government and industry organizations to stay updated on the latest attack techniques.
• Emergency response: Develop and rehearse response plans for cyberattacks, physical attacks, and disaster events.
• Third-party risk management: Evaluate the security capabilities of cloud service providers and clarify security responsibilities in contracts.

For enterprises that rely on data center operations, data center security should be incorporated into the enterprise risk management framework rather than being treated merely as a technical issue.## SecurityPost Insight

Data centers have become the digital hub of modern society and the focal point of security contests. From cyberattacks to military strikes, from community protests to policy restrictions, the multiple risks facing data centers expose our vulnerabilities in the pursuit of digitalization. For enterprises, this is not merely a matter for the IT department; it is a strategic decision at the board level. We recommend that enterprises elevate data center resilience to the board agenda and actively promote coordinated protection between industry and government. In the future, with the exponential growth in AI computing power demand, the security importance of data centers will further increase, and those enterprises that plan redundancy and strengthen resilience early will win the initiative amid uncertainty.
