A data center or colocation provider is one of the most important investments that a company can make these days.
In a nutshell, a data center can ensure the continuity of your business and make it almost impossible for your website (and internal company network) to go down fully in the event of a power outage or cyber-attack.
This provides a number of benefits, including increased security, better customer experiences, and more.
However, different data centers in the UK have different server limits, provide different amounts of power to their servers, and may offer different ancillary services. Finding the right UK data center for your business is crucial, particularly since you’ll want something that works over the long-term.
You’ll also likely want to find a data center with high uptime (as close to 100% as possible). Such data centers will have UTI certifications of Tier 2 or 3, indicating very high reliability.
Today, let's take a look at the 15 best UK datacenters. Each link will take you straight to the data center's main page so you can browse through what they offer in more detail. Let’s begin!

Perhaps this data center's most notable feature is its uninterrupted power availability. They feature a private distribution network that can provide 9 MVA directly to the data center site.
