TL:DR
- Data center operators invest in power redundancy, physical security and responsible resource consumption to protect against outages that can be costly.
- True power redundancy requires dual UPS systems on separate distribution paths, backup generators & regular testing to maintain continuous operations during failures.
- Advanced monitoring systems & predictive analytics at Equinix enable early detection of potential issues, ensuring proactive maintenance & uninterrupted performance for mission-critical operations.
The summer months are upon us. In many parts of the world, that means higher temperatures. Extreme heat can impact data centers by adding stress on cooling systems and increasing demand for energy. That’s why right now is the ideal time to revisit what’s involved with keeping data centers online, in spite of extreme weather.
The good news: Data center operators have continued to take steps to mitigate the impacts that weather may have on their operations. Uptime Intelligence’s 2026 annual outage analysis report found that outage frequency declined for the fifth consecutive year. However, the same report indicates that outages can still cause damage when they do occur. One in five respondents said that their most recent impactful outage cost more than $1 million.[1]
It is important for technical leaders to understand the risks facing their data center environments, and the steps that data center operators take to protect them. Let’s take a closer look at three aspects of data center risk mitigation:
- Power redundancy
- Physical security
- Responsible resource consumption, even during periods of peak demand
Power redundancy helps protect data centers from utility failures
When a data center environment lacks redundant power systems, that environment risks getting knocked offline during a power failure. This may sound like stating the obvious, but not everyone understands what it truly means to implement power redundancy within a data center.
It’s not just about deploying uninterruptible power supply (UPS) systems. It’s true that UPS systems provide immediate, emergency backup power from batteries, supercapacitors or flywheels, but even a UPS system can fail sometimes. Despite what the name suggests, a single UPS system isn’t a truly “uninterruptible” power source.
True N+1 power redundancy requires at least two UPS systems, with each on a different power distribution path. The paths themselves are also fully redundant, with each path having redundant switching, power distribution units (PDUs) and remote power panels (RPPs). This limits the risk of both UPS systems failing at the same time, for the same reason.
All Equinix colocation data centers include UPS systems with redundancy of N+1 or greater. They also have backup generator systems to protect against local utility failures. Both systems are tested on a regular basis. When a utility outage does occur, backup batteries activate immediately, and generators activate within seconds. These generators are capable of powering the entire facility for days or even weeks at a time. Our dedication to power redundancy is one reason Equinix can offer data center uptime of >99.9999%.
We work with our customers to make sure they’re able to take advantage of the redundancy we offer to meet their IT disaster recovery requirements. Our dual power redundancy can only benefit customers if they design their environments to leverage it, and we’re aligned to help them do that.
Physical security limits unauthorized access to data centers
The simple reason that data center security is so important is that data centers have become essential to our modern digital economy.
While cyber threats could be a concern for data centers, improper access to the facility is also a concern.
Attackers may attempt to enter data centers using old-school social engineering tactics; that is, talking their way past security using only a convincing story and an air of confidence. Bad actors may also attempt to gain access via:
- Tailgating, when an unauthorized visitor sneaks into the facility by following an authorized visitor
- Impersonation, when an unauthorized visitor attempts to enter the facility using an assumed identity
For all these reasons, we believe that people should play an important role in physical security for data centers. We like to say that data centers are the heartbeat of the digital world, and that heartbeat runs on people. We invest in our people because they help keep our data centers running and our customers happy. That’s certainly true when it comes to physical security.
Our people are an important line of defense against improper access to customers’ sensitive equipment. We empower them with certifications that help them understand and apply industry best practices for securing the facility. For instance, we operate in accordance with industry standards like Trusted Site Infrastructure (TSI) and regional standards like EN 50600 in Europe.
Our sites use five separate layers of physical security to prevent unauthorized access:
- The front door to the security lobby
- The security desk for check-in and identity verification
- The mantrap to control ingress to the facility
- The door to the colocation floor
- The gate to each individual cage or cabinet
Each of these layers plays a role in preventing unauthorized access to customer equipment, but they also create a clearly defined process for authorized visitors to gain access without delay or hassle. When a visitor does have a legitimate reason to enter the facility, we can help them get where they’re going quickly.
In addition to controlling access, we also perform continuous monitoring throughout our facilities. We also take the following steps to help address the threats facing our data centers:
- Sourcing intelligence information: We use regularly updated, expertly sourced intelligence feeds to prepare ourselves for the latest threats. We use this information to guide our on-site security measures. For instance, we may develop new training and educational programs to ensure our workforce is appropriately informed about emerging issues.
- Addressing insider threats: To protect against the threats posed by individuals who have previously been granted access to enter and work inside our facilities, Equinix maintains our Insider Threat Program (ITP). The ITP establishes best practices for gathering and reporting relevant, credible information related to insider threats.
Using resources responsibly supports long-term data center stability
There are resources that data centers cannot function without, and energy is obviously one of them. We talked above about how we optimize power redundancy within our data centers, and this is important to enable resilience. But there’s a wider conversation we should be having about how data center operators can support the long-term stability of energy grids.
There have been some concerns expressed about data center power usage. At Equinix, we believe that data center operators have a responsibility to be mindful about the energy we use. This is because we want to be a responsible member of the community, but it’s also because we understand the direct connection between grid stability and long-term data center reliability.
As a global colocation provider, we’re investing in local energy grids across many of the different communities we operate in. One way we do that is by partnering closely with utilities, regulators and regional system operators on solutions that enable necessary grid investment without burdening other ratepayers.
Energy efficiency is another important aspect of resource stability for data centers. It’s true that AI adoption can lead to denser hardware that uses more energy in the same rack footprint, but we can still aim to operate that hardware as efficiently as possible.
Equinix invested $36 million in efficiency improvements during 2025, including advanced cooling, intelligent monitoring and optimized design. As a result, we improved our global annualized average power usage effectiveness (PUE) by 5.3% year over year.
To be a responsible community member and prioritize long-term stability, data center operators can also consider water consumption. At Equinix, we do this by choosing different cooling technologies in different locations to balance the tradeoffs between water and energy. We’re also pursuing alternative water sources such as reclaimed water. We are already using reclaimed water for cooling purposes at sites in California, Virgina, Australia and Singapore, and we’re working to gain access to reclaimed water in other regions as well.
We factor climate-related physical risk criteria into data center site selection, including potential exposure to natural disasters, water risk and resource availability. We incorporate appropriate mitigation measures into the design and construction of new sites. We also periodically evaluate environmental threats to our data centers, including wildfires, flooding, high winds and drought, as part of our threat and risk assessments, ensuring we have the necessary mitigation strategies and business protections to address these threats.
What does this mean for technical leaders?
Digital businesses depend on their data centers. It’s important for leaders to recognize that they have options for how to get reliable, resilient data center services. At Equinix, we’re proud to offer our customers power redundancy, physical security and resource stability, all of which contribute to our unmatched uptime of >99.9999%.
However, it’s not enough for technical leaders just to know that these capabilities exist. That’s why we prioritize engaging with our customers to share these capabilities and unlock their full potential. We invite our existing customers to start a dialogue about the best ways to do this.
