CyrusOne Data Centers

Strategically positioned within Slough—one of the United Kingdom's most sought-after data center ecosystems—the CyrusOne LON3 facility delivers world-class technical infrastructure. Spanning 3,600 square meters (38,750 square feet) of premium, fully built-out whitespace, the site boasts an impressive 340 cm floor-to-ceiling clearance and a dedicated loading bay. It accommodates a highly flexible array of deployments, from shared rackspace and standard full or partial cabinets to expansive, secure private cages and dedicated bespoke suites.

Engineered to handle massive enterprise workloads, the facility commands an impressive 9 MW total IT load capacity. Uninterrupted power is guaranteed through an advanced distributed redundant UPS topology featuring a 10-minute battery buffer. During extended utility outages, the site seamlessly transitions to fully rated, distributed redundant LV standby generators armed with a 48-hour on-site fuel reserve. Strict environmental parameters are maintained by a highly efficient N+1 indirect adiabatic air-cooling system, guaranteeing optimal temperature and humidity at all times.

Built to act as a formidable digital communications hub, the data center features a highly secure, carrier-neutral Meet-Me-Room (MMR). This enables seamless, high-speed interconnects and provides extensive direct access to major global peering networks. To complement this robust connectivity ecosystem, expert 24/7 remote hands services are readily available to assist clients with immediate on-site technical interventions, deployments, and smooth hardware management.

Operating to rigorous Tier 3 standards, LON3 maintains absolute operational and data integrity with a premium suite of certifications, including PCI-DSS, ISO 27001, ISO 9001, and ISO 14001. The heavily fortified physical perimeter is protected by secure fencing, anti-tailgating mantrap portals, continuous CCTV surveillance, and multi-factor biometric and proximity card access controls. Furthermore, fire threats are instantly mitigated by highly sensitive VESDA (Very Early Smoke Detection Apparatus) technology paired with an advanced automated suppression mechanism.
