Best colocation provider of 2024

The best colocation providers allow you to move your business on to the next level. For while it's initially cheaper to rent your own IT hardware and infrastructure in the short-term (think traditional web hosting), as your business needs grow there comes a point when it becomes more economical to buy your own server hardware. 

However, you then need a data center to host your equipment. This is where colocation services come into play, where racks and cabinets are leased to you, enabling you to set up your own server hardware in the heart of a data center.

Making a decision on which provider to use is far from easy, and the question of which operation to pick might seem overwhelming, so here we'll feature some of the best in the industry. We've compared some of the best colocation providers around the world to see how they fare when it comes to meeting the requirements of your business. 

In our analysis we've taken a close look at latency, taking into account the number of available data centres a provider has and - just as importantly - their locations.

We've also looked at whether the colocation services are provided directly by the data center, or whether they are companies that lease cabinets from them while offering additional support options for added value.

The good news is that there are a wide range of options, with good networks across the US and further afield, and the industry is highly competitive. That means pricing will tend to be very affordable according to your needs. 

We've featured the best web hosting.

1. Equinix

The leading choice for uptime

Reasons to buy

+
Excellent distribution and hundreds of data centers
+
Good networks
+
Lots of options

Reasons to avoid

-
Support may not feel personal

Equinix boasts one of the biggest worldwide distributions, with over 240 data centers across 71 cities and 27 countries spanning five continents. Factor in the 99.9999% uptime, and you can see why it's the choice of 260+ Fortune 500 companies.

In terms of choice, Equinix has plenty. You can configure and support your deployments according to power needs in cage, suite, or server cabinet solutions, or even colocate in pods that act as dedicated rooms. There are also other options for mitigating risks which will prove attractive to financial services companies, and a range of virtualization opportunities.

Overall, the number of options could be potentially overwhelming, and as with many big service providers, small business customers may not feel they get the same personalized support that other SMB-focused colocation providers can offer.

Best across North America

2. Cyxtera

A solid network choice for US users

Reasons to buy

+
Good spread of data centers
+
Solid network
+
Custom options

Reasons to avoid

-
Predominantly North American-based

Cyxtera boasts over 60 data centers across four continents, with the backbone of these being spread across the US. This impressive coverage is partly due to its purchase of CenturyLink's hardware assets, though CenturyLink still provides the network connections.

In terms of options, Cyxtera offers plenty, as you'd expect from a big company. It also provides multiple levels of support and specifications according to individual business needs. It's also worth noting that the Cyxtera data centers are really nicely spread out across the US, which means that you should be able to minimize latency and lag issues across the country.

A nice extra touch is that you can actually use your own cabinets if you'd rather not go with those provided, which could be important if you have a particularly customized server setup and configuration – though note that for security reasons Cyxtera technicians will need to install it.

Overall, this is another major provider that should be able to deliver on the hardware support you need.

Best for eastern seaboard

3. Tierpoint

Top pick for those on the eastern seaboard

Reasons to buy

+
Large number of data centers
+
Good network reach
+
Optimized for Europe

Reasons to avoid

-
Possible latency issues with Asia

Tierpoint is a major North American provider, with over 40 data centers across the US. The central point to bear in mind here is that these tend to be in eastern states, which means in terms of connectivity they are ideally optimized for US and European operations, but latency issues may be a concern if connecting to Asia. 

There are plenty of options for colocating available, as might be expected. One particularly nice feature is a business continuity workspace, so that if you face a major task or recovery process, you can plug yourself into a private area while you try to get everything sorted out. Tierpoint also advertises migration services, to make any move to Tierpoint from another provider as seamless as possible.

Tierpoint offers a standard range of options that mean it should be easy to accommodate and support you. This company is one of the major players so should be able to deliver, just keep an eye on a location that works best for you.

Best eco-friendly

4. Iron Mountain

The Fortune 1000 pick

Reasons to buy

+
Backbone of connectivity
+
Presence in Europe and Asia

Reasons to avoid

-
Fewer data centers

Iron Mountain is a mid-range provider, with a string of 21 data centers including 9 locations in America, 4 in Europe and 6 in Asia. While that can't match the likes of Equinix in raw numbers, Iron Mountain more than delivers in other areas.

All Iron Mountain's data centers are 100% renewable powered, for instance, with natural cooling and leading-edge on-site solar power generation. (The company says its 2019 New Jersey solar power project was the largest solar installation of any data center in the US.)

The company puts a strong emphasis on compliance, too, with worldwide standards support including HIPAA, FISMA High, PCI-DSS, ISO 27001, ISO 50001, SOC2/3, and more.

Iron Mountain offers a huge range of colocation options, covering everything from simple server colocation and cabinets, up to private data center suites or fully dedicated data halls for the largest of projects.

Factor in the company's 30 years of experience, it's no surprise that Iron Mountain has built up a very impressive customer list, including big digital names such as Akamai and CBS Interactive.

Best for Texas

5. Data Foundry

Ideal for onsite expertise

Reasons to buy

+
Limited to Texas
+
Carrier neutral

Reasons to avoid

-
Contract renewals

Data Foundry is a major player in Texas, owning a handful of data centers across Austin and Houston. While this makes the company seem a little limited geographically, Texas has proven to be a strong center point for the best colocation providers and data operations across America. Using carrier-neutral data centers means that whichever US states your customers are in, you should be able to reach them with minimal lag or latency.

A particular selling point Data Foundry advertises is that not only has the company custom-built its data centers itself, but that all technicians are company employees rather than contractors, which means you should expect all the expertise you need to already be onsite.

The one caveat is to keep an eye on contract lengths, as you may want to avoid signing multi-year commitments if you find your IT needs change during the contract period.

Best for mission-critical apps

6. Digital Realty

The top environmental choice

Reasons to buy

+
Huge global presence
+
Many carriers
+
Good infrastructure

Reasons to avoid

-
Among the more expensive options

Digital Realty is one of the biggest players when it comes to colocation, with a truly global presence through a mixture of partnerships. The company owns 300+ data centers across 50+ cities, including 21 in America, 8 in Asia, and 22 in Europe and Africa.

Connectivity is a particular strong point, geared towards supporting mission-critical applications for finance, healthcare, and even social media companies.

While it offers the usual range of cabinets and cloud options, Digital Realty further makes an effort to ensure its data centers are as green as possible, winning various awards for the use of environmentally-friendly technology to minimize power and energy waste.

Although Digital Realty positions itself as a global player, another strength is local support, so you don't have to feel overwhelmed if you're a small business looking for a solution.

Best for cloud services

7. CoreSite

Ideally suited for cloud and network providers

Reasons to buy

+
Solid hardware and network
+
Interconnection options
+
Good spread of locations

Reasons to avoid

-
No data centers outside of USA

CoreSite is another significant player in the US market, with 28 data centers across 10+ markets, and direct connections to top platforms from AWS. Azure and Google Cloud, to Alibaba Cloud, Oracle Cloud and IBM Cloud.

While it offers standard colocation packages of cabinets, cages, and private suites, CoreSite also allows colocating companies to interconnect their hardware across multiple data centers, making them especially useful for cloud and network providers, as well as enterprises.

Overall, CoreSite is a solid provider backed up by excellent network hardware and IT infrastructure, with a good spread of locations and an impressive range of colocation options.

Best for mid-state

8. Flexential

The mid-state pick for SMBs

Reasons to buy

+
Data centers spread across the US
+
Good national connectivity

Reasons to avoid

-
Limited colocation centers

Flexential was formed in 2017 through the merger of Peak 10 and Viawest, both already established providers. The result is a network of 41 data centers across the US, with the caveat being that most are in mid-state locations. Also, these tend to be small data centers rather than regional behemoths, meaning that while Flexential has a good geographic spread, it may not be the best choice if you have mission-critical applications connecting to Europe and Asia.

That's also a strength, though, that earns its spot in the list of best colocation providers. While a number of data centers offer to monitor and manage your hardware, Flexential is one of those companies where you can realistically do so yourself without living on the eastern or western seaboards. 

However, not all of Flexential's data centers are available for colocation, so you'd need to check availability first. Otherwise, Flexential is a company that will particularly appeal to smaller and mid-range companies, and could be a very good place to grow, especially if you don't plan on needing a large volume of server hardware in the short-term.

Best for Asian markets

9. CDNetworks

Top choice for Asian markets

Reasons to buy

+
Strong presence in Asia
+
Good network connectivity

Reasons to avoid

-
Limited US locations
-
May need to delegate IT management

CDNetworks is best known for its global Content Network Delivery (CDN), but the company also provides a range of other cloud features: object storage, edge containers, a web application firewall, and, the reason for its inclusion here, some appealing colocation services.

The company has only 21 data centers, including eight in the US, eight in Asia and Oceania, and others in Russia, Saudi Arabia and Germany. But partnerships with more than 100 Tier 1 carriers ensures speedy and reliable connections, wherever your audience.

CDNetworks can't match the likes of Iron Mountain for colocation options, but it more than covers the basics, with dedicated racks, low or high power density, shared space or dedicated pages.

Support is covered via a 24/7 remote hands service. Although this can get you a response within 2 to 4 hours, it's good to see CDNetworks also offers a 'Next Business Day' service for smaller companies on a budget.

Overall, CDNetworks offers good connectivity globally, but you're probably going to get the most out of this provider if you're aiming for Asian markets in particular, and are happy to delegate a lot of your IT management.

Best for managed solutions

10. DataBank

Ideal if looking to delegate IT management

Reasons to buy

+
Locations across central US
+
Good connectivity
+
Managed services

Reasons to avoid

-
Less control over hardware

DataBank offers colocation from 70+ data centers situated across the US (plus a couple in the US and France), which the company says can bring your workloads to within 100 miles of 60% of the US population. Even better, it provides managed solutions so you can delegate your IT management to DataBank's own technicians.

As mentioned previously, this comes with positives and negatives, and you'll need to balance them in terms of ease-of-use versus less control over your hardware management. The latter, of course, may make DataBank particularly attractive if your business is too small to have an expert IT team. Even if you do have one, the data center locations are among the most accessible of the companies featured here.

As expected, DataBank offers a range of options, not least in terms of cabinets, cages, and custom suites, as well as cloud options. With good connectivity across the US, this could make DataBank an especially attractive colocation provider.


The best colocation providers in the UK

Best for the UK

(Image credit: Future)

11. Netwise Hosting

Perfect pick for London-based businesses

Reasons to buy

+
Advanced connectivity options
+
Useful supporting services

Reasons to avoid

-
Data centers in London only

Founded in 2005, Netwise Hosting is an experienced provider with its own data center in central London, and partner centers in Docklands.

Colocation plans start at £119 a month for a lockable 10U quarter rack, or £259 a month for a full rack. This only gets you a single power feed and a 1Gbps network connection, but you can upgrade to dual feed and 2 x 1Gbps lines for a total of only £60 a month, and there's plenty more power if you need it (you can even have a 2x10Gbps connection for £200 a month.)

There are plenty of advanced options here. Are you using MPLS (Multi Protocol Label Switching) to connect your systems, for instance? Netwise Hosting can support L2 and L3.

The company also provides a very complete set of colocation services, including migrating your server from another location, racking equipment for you, managing systems or providing 24/7 support.

If you're unsure about the options, the website has a Colocation Calculator where you're able to choose the plans and features you need, and get a price right away.

12. Zen Internet

Ideal if looking for generous support services

Reasons to buy

+
Experienced provider
+
Up to five Remote Hands sessions a month

Reasons to avoid

-
Only one data center

Zen Internet is best known as one of the UK's first ISPs, having been providing web access to the masses since 1995. But the company uses its networking expertise to support other services, too, including colocation in its Greater Manchester data center.

Simple shared rack plans were priced from £59 a month, with 1U of rack space, 0.5 amps of power, and your choice of a data transfer allowance or an allocation of fixed bandwidth allowance.  Now, you pay a monthly cost based on how much space, power and bandwidth you require and you'll need to get in touch with them for further information.

Still, you are covered by a generous service level agreement which guarantees 100% power availability, 99.999% for network and 99.97% HVAC (heat, ventilation and air conditioning), with a one hour 'at rack' guarantee in the event of any problems.

If any issues crop up, Zen's Remote Hands support service can check status indicators, reset or reboot your hardware, replace circuit patch leads and patch panel connections, and even change hot-swappable components, if you've provided spares. You get up to a generous five Remote Hands sessions a month, each lasting up to one hour – some hosts might restrict you to a single session of just 30 minutes.

13. Claranet

Ideal for flexible contracts

Reasons to buy

+
Big-name company
+
Five UK data centers

Reasons to avoid

-
No plans smaller than quarter rack

Claranet is a top European provider with more than 20 years’ experience in delivering managed IT services to businesses around the world.

The company manages multiple data centers, with five available for colocation. Your London options are Global Switch London East, Telecity Harbour Exchange Square and Telecity Sovereign House, and there are also centers in Hoddesdon (Hertfordshire) and Manchester.

Claranet doesn't try to compete with others for the lowest advertised price (in fact, it doesn't advertise a price at all – you have to contact the company and ask for a quote). There are no almost useless 1U plans, for instance: you must choose a quarter, half or full rack. As of late, the colocation page redirects to Hybrid Cloud section, so there might be some changes for colocation services.

Still, there's plenty to like here. Cabinets are all lockable to keep your hardware secure. Flexible power options ensure you get exactly what you need. You're able to access your server 24/7. There are flexible contracts available from a minimum of 30 days, with some benefits if you opt for longer terms (you get free installation if you sign up for three years). Well worth a look if you'd prefer to colocate with a big-name provider.

14. Fast2host

Value choice for UK users

Reasons to buy

+
Low starting price
+
Useful bundled extras

Reasons to avoid

-
Single data center

Colocation is often marketed as a high-end hosting solution for big corporations only, but the reality is very different. Even the smallest business can benefit from the extra speed and control you might get with a colocation plan, and if you choose the right provider, low prices and contracts as short as a month allow almost anyone to try the service out.

Fast2host won't be the most convenient colocation host for everyone. It only has a single data center in St Ives, Cambridgeshire. Customers with lesser plans (1U-3U) don't get 24/7 access to their hardware, and standard Remote Hands support is limited to a miserly 45 minutes a month (30 minutes for 1U-3U), even for full rack plans.

On the plus side, Fast2host offers real value, especially with the starter plans. The 1U rack space plan includes 0.8 amps of power, rather than the 0.5 amps typically provided elsewhere. The data transfer allowance is a generous 1.2TB a month. ICMP and HTTP monitoring, often an optional extra with other providers, comes for free here. A 100% SLA on power and 99.99% SLA on network availability will be good enough for most users, yet all this can be yours from as little as £55 a month.

If you need more, Fast2host's website makes it very easy to explore your options. There's no bulky comparison tables, and the company doesn't force you to contact them to get a quote: just click a plan (1U-5U, quarter, half or full rack), then you can instantly view the details and place your order in a couple of clicks.


Best colocation provider FAQs

How to choose the best colocation provider for you

There are a number of considerations you'll need to take into account when deciding which colocation provider to opt for. 

If your business has mission-critical needs then you'll want to reduce latency. Additionally, you may need to look for hosting on the west coast for optimal Asian connections, east coast for European ones, or mid-state for the best general connectivity across the US. However, you need to ensure that the geographic siting works for you, by balancing a combination of network connectivity, resiliency, and disaster recovery considerations, as well as ease of access.

All providers should be able to offer different cabinet sizes to suit you, plus different power configurations according to needs, on top of standard security and redundancy measures across the data center itself to protect client hardware and ensure it runs even in the event of a power outage.

The best colocation providers: How we test

In our wide-ranging list of the best colocation providers in both the USA and the UK, we've looked closely at some of the key factors that will form your decision on which is best suited for your business. 

Given the importance of latency, speed, and security, the location of the colocation provider is key, and we've featured a range of providers, from those with a global reach to others that have a less expansive scope that may be more suited to a smaller, local business. 

We also looked into cost and pricing models, and noted what security and uptime guarantees are promised by each provider. We also made a note of the level of support provided, whether this is offered 24 hours a day or limited to certain times. We also compared the levels of management offered, with some providers able to provide fully-managed IT solutions.
