With colocation you rent space in UKFast’s ISO-accredited UK-based data centres to securely house and power your server. So you retain ownership and control of your physical server – UKFast simply houses and protects it for you.
Colocation is the ultimate solution if you want the flexibility and control of owning a server but don’t have the in-house resource or space to house and securely store it yourself. It’s also an ideal option if you’ve already purchased a server and want to continue to gain returns on the investment made.
