How to choose the right colocation data centre in London to fit your needs

Colocation facilities are relatively new innovations in the business and technology landscape, but they are growing quickly. In fact, the market for colocation facilities in the United Kingdom alone is worth more than 2 billion pounds sterling every year.

Of course, not all colocation data centres are created equal. If you want to find the best services possible, you’ll probably have to shop around a little.

So how can you make sure that you picked the right colocation data centre for your unique situation? Read on to learn all about the most important considerations to keep in mind when picking a colocation data centre.

1. Pick a data centre with the right power density

Using a colocation data centre is an investment in the long-term future. That is why it is important that the data centre that you choose is also oriented towards the future. If a data centre has enough power density for current technologies, but not for future ones, it will not be able to adequately provide for your long-term needs.

For that reason, it is important to pick a data centre with a high enough power density to cover all of your current needs as well as a significant increase in your demand looking ahead. That way, when your needs inevitably increase in the future, your data centre will still be able to provide what you are looking for.

In particular, you will want to watch out for colocation data centres that came to be before the density boom. Many of these are unable to support more than 2kW per cabinet.

For that reason, you might want to go with a data centre that was designed and built more recently. More recent constructions are more likely to integrate the latest developments in technology.

2. The best colocation London has to offer should provide network carrier redundancy

No matter how advanced everything else about your system is, your connectivity is ultimately reliant on networks and carriers. If the connectivity of a given data centre relies on only a single path network, then no matter how well designed everything else is about the facility, if the carrier suffers from problems, so will the data centre.

For that reason, the best data centre should provide network redundancy. When a colocation data centre has many networks through which clients can access connectivity, it is less likely to run into potential problems.

3. Find data centres in the right location

When it comes to technological solutions like colocation data centres, people sometimes make the mistake of underestimating the importance of physical location. Physical location may not be as important for technological solutions as it is for other kinds of solutions, but it still makes a significant impact on service.

One thing to keep in mind is vulnerability to natural disasters. You might want to pick a colocation data centre that is in a very safe part of the world.

At the same time, the closer your data centre is to you, the better that can often be for ongoing management and maintenance. You’ll also want your systems to distribute services as close to your end users as possible, as this will ensure the best possible low-latency access.

On top of that, there are some times when you need to physically access your data centre. In those cases, you will not want it to be too far away. For that reason as well, the ideal data centre will not be more than one or two hours of transportation away. 

4. Pick data centres with the right physical security

In the same way that people neglect the importance of physical location, they sometimes neglect the importance of physical security. Physical security is still a major factor even in technological solutions. Everything in the digital world is still reliant on physical systems.

For that reason, you should look into security practices at each data centre. The data centres with the best security practices can provide more reliable service.

5. The best colocation data centres have backup plans

Some people are so confident in their systems that they feel they do not need backup plans. However, true certainty comes when you are sure your system is solid, and you have a backup plan in place regardless. You should find a data centre operator that can assist with your own disaster recovery plans.

Not having a business continuity plan is a red flag. You should absolutely pick a data centre that is fully able to deploy your systems with business continuity in mind.

And the more layers there are in the backup plan, the better. Offering services in multiple on-net locations, for example, would be one excellent way of achieving this.

6. Find a data centre with proper compliance

Make sure to ask about the compliance of each data centre you look at. However, you should also verify what they tell you. After all, any data centre without proper compliance is probably not going to tell you about it.

Instead, you should look up the certification of your data centre.

Business Continuity: why London data centres are essential

Data shows that only half of UK organisations are confident in their business continuity plan. The importance of a BC plan is evident in how many businesses were affected by the pandemic.

Are you concerned for the well-being of your company? Keep reading to find out the best way to protect yourself and your organisation.

What is Business Continuity?

Business continuity is a term that serves to explain how a company might continue its essential functions even during an unforeseen event. These events can include the following:

  • Natural disaster
  • An outbreak of a disease
  • Fire / flood
  • Cyberattacks
  • Industry Strike

A business continuity plan (BCP) includes essential items and procedures that are to be followed in the event of a disaster, whether they are small or large. In addition, it often covers practices that allow the company to function with minimal disruption during the said event.

What is Disaster Recovery?

During your research, you may have come across the term “disaster recovery.” Often, business continuity and disaster recovery are used interchangeably; this is a misconception.

A disaster recovery plan often deals with data protection and cyberattacks. However, it also protects against events such as a system failure or even a device failure. 

Business Continuity vs Disaster Recovery

Business continuity is often referred to as the plan needed in case of a disastrous event. It is planned ahead of time and implemented during an unforeseen event. In contrast, disaster recovery is the plan that is executed after the event.

Another key difference is that a disaster recovery plan focuses more on recovering the IT infrastructure of the business. In contrast, the BCP focuses more on the daily operations of the organisation. 

What does a BCDR plan look like?

A BCDR plan tackles the issues that arise during an unforeseen event. It often includes the ‘four-R’ predefined plan to allow for continuous operations. The four-R plan is as follows:

  • Respond
  • Recover
  • Resume
  • Restore

While this may give you an idea of a BCDR plan, it is essential to include some key components in your plan:

Contact info and SLAs

A business continuity plan should include the correct contact information and service level agreements (SLAs) required to identify and inform the right parties. These parties include emergency responders, stakeholders, key staff members, managers, data security, and any service providers.

This information should be the first step in your plan, as it is crucial to inform the right members of your team.


Business impact analysis helps predict what procedures could be impacted by the disaster. This analysis can help you identify and gather information to prepare for the event.

The BIA will help you analyse items such as extra expenses, revenue loss, reputation damage, dependencies, repercussions of disruptions, and more.

Risk assessment

A risk assessment identifies the risks that could trigger a disastrous event. When completing a risk assessment, your company will need to identify possible hazards such as a fire, flood, terrorism, pandemic, and cyber-attack.

Additionally, you will need to assess the assets at risk, much like the business impact analysis. 


Once you have your contact information together, you will also need to determine the communications method of contacting the critical members involved. Finally, you will need to assess how to reach each group effectively. These groups include your employees, customers and clients, and providers.

Communication is key in any relationship, especially in business. However, in the event of a pandemic such as COVID, it is essential to communicate the company’s needs to your employees, the restriction on which you can operate to your clients, and what your shareholders can expect until the disaster is alleviated.


Arguably, the most important aspect of your plan is to test it. Having a plan meets the minimum requirements but knowing that it works is critical. Additionally, it is imperative to practice the plan so that your team knows what to do in such an event.

While you are testing the plan, look for gaps and weaknesses in your plan. You may notice that, in theory, the plan works well. However, you need to update and document when the plan falls through in practice. 

Data centres: which solution is right for you?

A proper BC plan includes a data recovery plan to restore the servers and systems of your organisation. This data is different for each company; however, you’ll need to recover software, hardware, and basic operations for each company.

The first step to recovering your data is a regular backup. You can do this in-house; however, in the case of a fire, flood, or earthquake, you risk losing the data that is essential to your company’s operations.

However, a data centre provides a safe and secure place for your organisation to store essential data. When you are looking for a reputable data centre, consider the precaution the centre takes to protect the data. Ask yourself questions like:

  • Is it cooled?
  • What hardware is used?
  • What power system is in place?
  • Is the centre monitored 24/7?

9 things to look for in your London data centre

Did you know there are around 285 colocation data centres in the United Kingdom? As the UK capital, London is the perfect place to house your critical infrastructure. But do you fully understand what makes a good one?

London has a lot to offer, from sound infrastructure to geographical safety. Read on as we discuss nine things to look for in your London data centre partner.

1. Security

Security comes in both digital and physical from when referring to top-quality London data centres.

Data centres can also be attacked physically. Therefore, you need to check the security of the facility itself. It should be monitored 24 hours a day with video surveillance equipment. 

2. Power redundancy

When you have a business that runs online, you need to make sure it is operating at full capacity through all eventualities. If you have a critical system that can not go down, what happens if a data centre runs out of power? 

One factor your London data centre needs is a secondary electrical connection. Most facilities will have this, and N+1 grid connectivity with a second power source is essential. 

Any failures in the power will not lead to a shutdown with this in place. When choosing a centre, ask what electrical backups they have. 

3. A good location

When you choose a data centre that is a long way off, then your networking costs increase. When it is closer to your place of operations, it is easier to respond when any problems or issues arise. This is what makes a London data centre such a great option for businesses in the city. 

Lights out facilities is the term used for centres managed remotely. Preferred by some, they are risk-averse and cost-effective, as management is away from areas prone to natural disasters. However, this is not a problem that impacts the city of London.  

This makes a data centre in London a great choice all around. They are safe and with so much easy access to the city, can be visited whenever you need to check on them. 

4. Provision of an SLA

service level agreement (SLA) is a binding contract that sets out what the data centre will provide you with. This needs to be studied in-depth, as it may contain hidden caveats within the small print. When something goes wrong, you don’t want the provider to leave you high and dry because you didn’t read it properly. 

Don’t be afraid to address these issues. If you want something added or removed, then discuss it with them. This may also help them get a better understanding of the coverage and service you desire. 

One area that is often hard to understand is accountability for security. Make this as clear as possible in your SLA. All of this should be discussed during your search, not when it comes to signing the contract.

5. 24 hour support

Problems can occur at any time. This does not just mean the middle of the night, but also on every day of the week, every single day of the year. Failure is not an option, because it costs people time and revenue. That is why the centre needs to be monitored and staffed around the clock. 

That does not mean staffing at the centre has to be consistent. In downtimes, less staff may be onsite or monitoring. However, someone must always be there to answer phone calls and give assistance. 

6. Reputation

Checking the reputation does not mean you won’t find unknown London data centres that are good. It is just that with ones that have a great reputation, you get a degree of certainty regarding their level of service. Speak to other business leaders and managers about who they use and get recommendations. 

In addition, when you sign up for a data centre you will be working together for a few years. You need to know they have a level of professionalism and service that will see you through. Ask the company themselves to provide references and testimonials to support their credibility. 

7. Geo diversity

Despite being an extremely safe place for a data centre, it is possible that accidents may happen. When they do and centres go out of action, you need to know the company has other centres across the country or region. 

If a disaster befalls the centre then another can keep your business up and running. Discuss this and see where their other centres are located. 

8. Certifications

Like any industry, the data providers will have a number of compliance certifications. These are to protect the centre legally and safeguard you as a customer.

In addition to this, your industry itself may be regulated and have compliance, which the data centre needs to know about. For example, if you have healthcare records and the data centre does not understand the compliance related to record-keeping, then you may be liable. 

9. Data capacity

Data capacity for your London data centre needs to be scalable. Technology is constantly growing and so are the needs of your business. The data centre needs to have the capacity to provide for you, then be able to forecast what else you may need, and be able to increase it quickly. 

Some data centres are huge and can support Amazon sized websites, while others may be much smaller. None are wrong or right, as long as they have the capacity to serve you now and in the future. 

Selecting a London data centre

Now you know the benefits of a London data centre, you just need to find one suitable for your business. Speak with a number of providers and make sure to go through the SLA in depth. 

Your first stop should be Netwise. We have colocation centres in the capital with state of the art facilities. Get in touch today and let us keep you connected.

A small business guide to a London data centre

Decades ago, society was content with simple TV broadcasts from only a few channels, and communication was as simple as snail-mail. When computers first came on the scene they were giant machines that would occupy whole rooms.

But as technology has evolved, computers and equipment have shrunk and become cheaper. With this evolution has come rising data processing demands which show no sign of slowing down.

As technological advances continue to change the way companies do business, the need for data and power increases. Data centres are the powerhouses of the industrial world, and a London data centre may be just the thing you need. 

What is a data centre?

The internet is now considered a daily essential, and almost everybody owns a smartphone, allowing 24/7 connection to the online world. With over 60% of the world’s population online at any given time, the internet plays a huge role in our lives. This means the demand for real-time data transmission is at an all-time high.

The need for computers and other networking equipment that can handle these requests was the driver for the emersion of the modern data centre.

Data centres are computing and networking facilities tasked to collect, store, process, and distribute data. They are responsible for data backup and recovery, as well as networking. 

Data centres connect communication networks so users can access information remotely. They host websites and manage e-mails and messaging services. Data centres also support cloud storage and e-commerce transactions. 

Importance of data centres

Almost every modern business needs a business data centre. Large corporations or government institutions may choose to build and manage them in-house if they have the resources, but most companies choose to rent services at colocation facilities.

Companies that handle finance, telecommunication, retail, education and social networking services process tons of information daily. Any business that produces or uses data requires a data centre to optimise running its operations. Data centres offer fast secure access to data that cannot be matched.

The idea of storing data and resources on home or work computers is quickly being replaced by an offshore storage mentality. Many companies are migrating their data to data centre services to reduce the cost of running in-house servers and to ensure failsafe reliability that cannot be achieved in the home or workplace. 

What Netwise’s London data centres can do for you

Data centres in London are far more than just safe and secure facilities equipped with reliable power and network access. They are quickly becoming a valuable addition to many businesses, as a dependable extension of their IT team.

Power outage protection

Onsite power failures are incurable when they result in a loss of data. Technological and natural power outages can cause disaster for an organisation. Loss of power for as little as 1/50 of a second can trigger events that can keep equipment unavailable for anywhere from 15 minutes to several hours. 

Outsourcing control to reduce the impact of a power failure is a great way to ensure this doesn’t happen to you. Date centres make use of both grid power and independent generators and UPS’s. This means you’ll be protecting yourself against power outages and ensuring your servers are never out of action.

What are the services that a colocation data centre offers?

Many businesses are choosing to host their servers and other critical equipment with colocation data centre providers rather than managing this in-house. Let’s look at some of the services offered by colocation providers and why you should consider making the switch.

Projections show the colocation data centre market growing by more than 13 per cent annually between 2021 and 2028. It’s an industry that’s expected to be worth more than $117 billion at that point.

What is a colocation data centre?

A colocation data centre is a facility that can host your servers and other critical IT infrastructure for you.

Rather than keeping this equipment on-site at your own premises, the colocation centre provides the physical space and resources to operate this on your behalf with much greater success. You still have full access to your equipment, but it’s housed inside the data centre and uses its network, cooling, and other related infrastructure.

It’s important to note that in a colocation arrangement, you still own the equipment. You’re not renting the hardware from the data centre, only the space and services needed for its operation.

Services offered by colocation data centres

Using a colocation centre (also known as “colo”) gives you the flexibility of managing your own equipment without having to pay for and maintain the infrastructure in-house. These providers offer several services.

1. Better infrastructure

A colocation data centre operator such as London-based Netwise need to maintain high-quality, reliable infrastructure to attract customers. They host equipment for many companies so their resources are typically much better than the average business would have in-house.


Colocation providers offer redundant, high-capacity power feeds to ensure your servers stay online and accessible. This includes UPS protection options for short-term outages and diesel generators with 48-hour on-site fuel supplies.

Network connectivity

To provide the bandwidth required to run dozens or even hundreds of servers, a data centre offers high-speed internet connections with the option to choose from many different network providers. This ensures that there’s no distinguishable difference in latency between a colocated server and an on-site server.

The level of network connectivity in a data centre offers better performance than a local connection.


Data centres can also provide better facilities than hosting your servers in-house. They use the latest cooling technologies, a high degree of physical security, and more modern rack mount systems than you may have available locally.

2. Uptime guarantees

If you’re hosting your server in-house, any downtime is your responsibility. Colocation providers offer service level agreements (SLA) that include uptime guarantees.

Netwise offers a 99.999% uptime guarantee, giving you the peace of mind that your servers will be available when you need them most.

3. Multiple geographic locations

Some colocation data centres, like Netwise, offer several geographic locations to choose from. This lets you host your server in a location of your choice, whether that’s one that physically close to your business or one that’s closer to your customers.

This lets you minimize your server’s latency by locating it closer to where the majority of its traffic comes from as well as have it nearby if your technicians are handling the maintenance.

4. Physical and network security

Most colocation providers provide a high level of physical security including guards, 24/7/365 surveillance systems, and biometric authorisation systems. This helps protect your servers from unauthorized in-person access.

They also provide better network security than many companies can maintain in-house. They stay on the leading edge of technological advances in network security, both in the tools they use and the training they provide their staff.

Maintaining the same degree of security in-house would require constant training for your IT staff as well as considerable costs for the latest equipment.

5. Cost savings

Your company could handle most of the services in this list in-house if you wanted. But the cost to do so would be much higher than the fees you’ll pay a colocation provider.

You would need to pay for faster network connections, new equipment, and other infrastructure costs. Some of those would be one-time costs while others would be ongoing.

You would also face higher payroll costs for training and maintaining round-the-clock support staff.

6. Service and support

When you host your servers in a data centre, you can choose to have your technical staff handle the maintenance or you can set up a support contract with the data centre provider. You may also want to consider a hybrid approach, with the data centre staff handling some tasks and your technicians handling others.

It may be more cost-effective for the provider’s staff to handle things like replacing a defective part or upgrading an internal component on your server. This avoids the need to send your technicians to the data centre to do the work.

7. Scalability

Colocation data centres have plenty of space for growth. If you want to add a new server or some other type of hardware to your network, they’ll most likely have the physical space and rack capacity to do so quickly.

If you’re hosting your server on-site, the amount of space you have available could limit your expansion options. In a case like that, you might face considerable capital costs to expand your server room or move to a larger facility.
