Houston’s a major player when it comes to business – energy, healthcare, tech, finance, you name it. And whether you’re running real-time analytics, managing sensitive data, or hosting customer-facing platforms, the backbone of it all is the data centre you choose; you want security, reliability, and the right kind of support. You also want something that won’t leave you scrambling during the next storm. So here’s a closer look at some of the best data centres in Houston for businesses that take uptime seriously.
TRG Datacenter
TRG Datacenter is purpose-built, not just a retrofitted warehouse. It’s located outside the floodplain and elevated above ground level, with indoor generators and waterless cooling – all designed to keep things running even in extreme weather. They also include 24/7 remote hands at no extra cost and back their uptime with a free-month guarantee if they ever fall short. If you’re after resilience and real support without jumping through hoops, TRG is a strong place to start.
DataBank
DataBank operates multiple large facilities across Houston, including a three-site campus and another location in the Galleria area, and together, they offer serious capacity and connectivity, plus access to dozens of carriers and public cloud on-ramps. Their centres are designed to meet strict compliance standards and are well-suited for industries like healthcare, finance, and energy. If your company needs scale, redundancy, and plenty of space to grow, DataBank’s infrastructure has you covered.
Equinix
Equinix’s Houston facility is a hub for interconnection, and that means it’s packed with carriers, cloud platforms, and business partners all linked together, so data can move quickly and efficiently, and it’s especially useful if your operations rely on low-latency connections or span multiple clouds and service providers. Equinix is also known for its global reach and sustainability efforts, which can make a difference if your business has broader digital infrastructure plans.
Digital Realty
Digital Realty has a strong presence in Houston with a facility on the north side of the city. It’s built for enterprise clients, with plenty of room for expansion and the kind of redundancy that ticks all the boxes for IT teams, and the on-site service ecosystem makes it easy to scale or adjust your setup as needed, making it ideal for companies that want a reliable platform to grow on without sacrificing stability or security.
CyrusOne
CyrusOne runs two data centres in Houston – one in Greenspoint and another in the Galleria district, and they’re known for high-density power capabilities, which is great if your infrastructure includes a lot of compute-heavy workloads. CyrusOne is often chosen by businesses in finance and tech that need a mix of power, connectivity, and flexibility because it’s a bit more of a high-performance environment, so it works well for companies with demanding hardware requirements.
Netrality
Located right in the heart of downtown Houston, Netrality’s facility at 1301 Fannin is all about interconnectivity; it’s one of the most fiber-rich buildings in the city, making it a go-to for businesses that need strong carrier options and fast connections. If your work is latency-sensitive or relies on tight integration with multiple partners, this is a good choice, and a bonus is that it’s also known for being highly resilient, with multiple power layers built in.
Data Foundry
With two facilities in Houston, Data Foundry has built a reputation for excellent support and strong compliance and their sites were designed from the ground up, not just retrofitted, plus they’ve been serving Houston businesses for decades. They’re a reliable option for organizations in regulated industries that need direct access to technical staff and consistent service, so if you want that extra layer of local expertise and managed options, they’re worth a look.
FIBERTOWN
FIBERTOWN is a smaller facility near the airport, but it that doesn’t mean it’s not a great option. It offers all the essentials – redundant power, strong security, and carrier neutrality – without the overhead of some larger centres, and it’s especially useful for small to mid-size businesses that need high availability but don’t require massive amounts of floor space. Plus, it has a more personal feel, which some companies genuinely prefer.
Stream Data Centers
Stream operates a large facility in The Woodlands that’s built for growth, it can scale with your business, from a single cabinet to multi-megawatt deployments. It’s also designed to support newer use cases, like AI and machine learning workloads. If you’re thinking long-term and need room to expand, this is one to keep in mind.
Quasar Data Center
Quasar’s downtown location focuses on interconnection and quick access, so it’s a good choice for businesses that need to move data fast, like media companies, content platforms, and trading firms. It may not be the largest option on the list, but what it offers in connectivity and location can make a real difference if you’re operating in latency-sensitive environments.
Cogent
Cogent’s facility north of the city offers a practical option for businesses that need colocation without too many extras. It provides solid power and network access and works well for ISPs, telcos, or any organization looking for a dependable footprint at a more accessible price point, and as long as you don’t need anything over the top but care about performance, Cogent keeps it simple and effective.
iland
Now part of a larger cloud services company, iland started in Houston and still offers a hybrid of colocation and cloud-based services. They’re especially good if you need disaster recovery or backup-as-a-service alongside your physical infrastructure, and it’s a flexible option for businesses that are shifting between on-prem and cloud models or looking to simplify continuity planning.
Conclusion
There’s no shortage of data centres in Houston, but not all of them are built the same – or for the same kind of business. Some give you massive scale and endless bandwidth, and others focus on high-touch service, smart redundancy, or deep cloud integration.
If you want a full-service facility with proven resilience and great support, TRG stands out as a strong choice, and for big enterprise needs, DataBank and Digital Realty offer serious scale. And if your priority is interconnectivity and fast access to networks, Equinix, Netrality, and Quasar are all worth a look.
The good news is that whether you’re hosting apps, backing up critical systems, or building a full disaster recovery setup, Houston has a provider that fits. All you’ve got to do is work out what matters most to your business and pick the place that matches.
