The Technology behind 4UHosting

All hosting companies are not the same. We know that to provide you with the best quality UK Web Hosting it is important to invest in a good infrastructure, quality hardware and the latest hosting technology...

AMD Epyc logo

We custom build our own servers from the highest quality components, selecting the best of every element to produce a reliable web hosting platform for our customers sites.

In 2019 we switched from Intel to AMD's amazing EPYC range of processors, with a minimum of 32 logical cores per server. We've been amazed by the blistering performance and I/O throughput of this platform.

SSD hard drive
Seagate & Samsung

Reliable storage is vital to the running of high availability computer systems. Seagate and Samsung Enterprise drives provide our customers with the highest possible quality disk space for their Web Hosting.

We use a combination of mechanical and solid state drives in our high performance web servers for high speed, energy efficiency and low failure rates.

Supermicro Logo

Our server chassis and mainboards are manufactured by Supermicro. We have been using their components exclusively for over ten years due to their outstanding price / performance ratio and extremely high reliability.

Supermicro based servers are also very energy efficient. providing "Green Technology" is a primary objective in the design of their products.

Winners Rosette
How We Differ

Many other low cost web hosts maximise their profits by using cheap hardware and components that might be found in home computers rather than servers.

We know that availability is important to our customers, so we have built our infrastructure without cutting any corners or compromising on quality. This is reflected in the very low failure rates of our servers.

The Data Centre

A secure and resilient base for our hardware

YO26 DC - inside server racks


A great home for your website. We have been using Bytemark's YO26 data centre in York since 2019. This is a recently built facility with a high level of resilience, security and connectivity.

The building can operate on generator power indefinitely, should there be a loss of mains power. It's a fantastic modern facility only 15 minutes from our offices.

YO26 DC - Security camera


The data centre has 24 hour security and CCTV coverage points on all internal and external entry and exit points, as well as between rack aisles from which images are recorded and stored.

With anti-tailgating measures, the site operates a strict photo ID and electronic fob entry system for access to the building and there is manned security on site on a 24/7 basis.

YO26 DC - Engineer at fuse box


With 1MVA of power,The facility has more than enough to feed our server racks.

In the event of a mains power failure, the resilient power backup system delivered by N+1 UPS feeds and 24 hour runtime generators will seamlessly take over to ensure that there is a consistent source of power to the data centre.

YO26 DC - Hands holding world globes


The data floor is fully monitored and implements Airedale SmartCool units providing cooling with N+1 resiliency. These switch to fresh air cooling when the temperature drops below 21.5C

With the latest fire protection provided by an FM200 suppression system, with VESDA early detection, staff are alerted at the earliest possible sign of fire.

The Network

Speed - Resilience - Reliability

Network Diagram

Fully Resilient Network

As you may be aware, the internet is made up of lots of interconnected networks that rely on each other. It is "a network of networks". We utilise a multi-homed network via our specialist providers that gives us a robust and flexible infrastructure, with the highest quality bandwidth available.

Network switch with cables


The state of the art multi-homed core network benefits from a full 10Gbps of connectivity. The infrastructure can transparently tolerate the failure of any link or piece of equipment.

With points of presence in York, Leeds, Manchester, and London, along with extensive peering, we utilise a robust, scalable and reliable network for our customers.

MPLS Diagram


MPLS is a much more efficient way of routing packets of data over the internet. The packets contain extra information about how and where to send the data, this speeds up the process greatly.

Networks that do not use MPLS are forced to analyse each packet header to determine where and how it should be sent. This results in an overhead and loss of performance.

By utilising an MPLS network, we are providing you with an ultra fast and efficient internet connection for your website and Email.

Another network switch with cables


Our bandwidth is provided via three tier-1 transit providers NTT, GTT and Cogent. Extensive peering is also carried out in the UK, directly with many other providers, including the top six ISP's.

Using three transit providers offers a great deal of resiliency and peace of mind. We are also now introducing IPV6 into all our new web servers.

Cloudlinux OS

Stable - Secure - Scaleable

Superior Server Stability

CloudLinux Diagram

We use CloudLinux on our Web Hosting servers. This is a customized operating system designed specifically for our industry. CloudLinux is the choice for web hosting providers because of the stable environment it provides even in the most extreme hosting situations.

In a traditional hosting environment each customer shares an overall set of resources and there is little control to prevent one site from overloading the server.

Without CloudLinux, If one site suddenly experiences a big resource spike from a large amount of traffic, poorly written script, or a denial of service attack, all the other sites on the server are also effected.

CloudLinux isolates each hosting account into its own lightweight virtualized environment (LVE) and gives each one a predetermined amount of resources. If one customer suddenly get's a huge amount of traffic any ill effects will be contained to only that customer.

So if you are running a busy site that starts to use too much in way of resources, it may get "throttled". This may cause it to slow down, but your site will stay online. If this happens regularly, you can contact us to discuss increasing your resource allocation.

CloudLinux Logo

CageFs is part of CloudLinux. It is a virtualised file system that puts each web hosting account into its own "cage", isolating it completely from all the other accounts on the system. With CageFS, Each User will not see any other users, and would have no way to detect the presence of other users & their usernames on the server. This effectively turns your web hosting account into it's own virtual private server, providing a much higher level of security over traditional methods.

CpGuard Logo

Since 2019 we have been protecting our servers and customers with CpGuard. It's an automated security solution that combines a web application firewall (WAF), intrusion detection, virus and malware checking along with a proactive auto cleaning system that prevents zero day attacks. You can rest assured that with 4UHosting, you are covered with the most cutting edge and reliable security software available in the industry today.

What is cPanel ?

cPanel is the industry leading Web Hosting control panel. We have been using cPanel on our platform since 2003.

The software is being continually developed and improved, with new updates and features being released on a regular basis.

We are an official cPanel partner and we believe that this is truly the best web hosting platform available today.

MailScanner Anti Spam

A fully featured premium Anti Spam solution included FREE with all our UK Web Hosting plans.

Spam generic image with laptop and people
78% of all email is spam. That's a frightening statistic and sadly it seems that the spam is here to stay, with no way of preventing unsolicited email from being sent, all we can do is use anti spam software to block bad senders and filter out the legitimate messages, leaving the spam behind and your inbox clean.
Server racks and people
Advanced System
We use the Mailscanner software on our own hardware. It works to block spam before it reaches your inbox by cleverly filtering out the bad senders. Servers that are not sending legitimate Email are automatically rejected via the use of unique policy rules that are updated many times a day, coupled with more conventional spam filtering.

Integrated Interface
The Anti Spam interface can be accessed from the cPanel area where you have full control. You can see logs and info relating to the delivery of messages as well as the ability to fine tune your anti spam settings to your liking and to add exemptions for senders that you want to bypass the filtering.
