Our two data centers in Central Europe offer a reliable and secure environment for your servers and corporate IT. Rely on top-tier infrastructure and a skilled technical team that is always ready to support you.
MasterDC data centers are protected by a six-layer security system, including biometric authentication for access control. We actively monitor the latest security trends and implement them in practice. Supported by our in-house CSIRT team and our active role in the FENIX project.
We have been around since the days when Amazon was selling music, Google had just registered its domain, and Facebook did not exist. Since then, we have gained a wealth of experience that our clients and partners benefit from on a daily basis.
Two is better than one. With data centers in both Prague and Brno, Czechia, you gain real flexibility – whether you are backing up to a secondary location or setting up a geocluster across multiple sites.
Our data centers are built with fully redundant power and network connectivity. Backup power sources and independent network routes ensure uninterrupted operation of your systems.
Access to our data centers is continuously monitored by on-site physical security. Members of the MasterDC technical support team are also present 24/7. All entry and movement within the facility is tracked by a certified electronic security system and CCTV monitoring with recording. PIR sensors detect and alert on any suspicious movement.
Entry to the data center is only permitted when accompanied by an authorised staff member. That person must identify themselves at a two-zone access point using a multimodal RFID/PIN reader and biometric authentication, specifically, vein pattern recognition. The vein pattern database is encrypted and completely inaccessible to unauthorised individuals.
Each data center is equipped with an automated fire protection system featuring smoke and heat detectors. Fire suppression is handled by an environmentally friendly gas system using FM200 a solution that is both server-safe and eco-conscious.
The hosted systems are powered by two independent 230 V AC power branches. If one branch requires maintenance or experiences a failure, the other remains fully operational and takes over seamlessly. Each branch draws power from dedicated high-voltage substations used exclusively for the data center, with no external sharing.
Our cooling units deliver up to 100 kW of cooling capacity and are configured in an N+1 redundancy setup. Cooling circuits are switched on and off as needed, with electronic regulation in selected rooms. Each hall is equipped with raised floors, cold aisle containment, and hot aisle separation. Temperatures in the cold aisles are maintained between 22–25 °C, with relative humidity kept within 40–60%.
Each power branch is backed by online UPS systems with isolated battery modules to safeguard against unexpected electrical fluctuations. In case of extended outages, 2N+1 diesel generators automatically start after 40 seconds. They are tested monthly and can operate for at least 24 hours without refueling, with fuel delivery contracts in place to ensure uninterrupted service.
The MasterDC core network is fully redundant, with every node connected via at least two independent routes. In the event of a line failure, traffic is automatically rerouted through backup connections, ensuring high availability at all times. Our network is built on an L3 leaf-spine architecture utilizing 40 and 100 GbE technologies. We provide connectivity through Arelion and RETN, and maintain direct peering links with major Czech operators such as O2 and UPC.
Our network infrastructure is protected against DDoS attacks and continuously monitored by our dedicated CSIRT team. As members of the FENIX project, we also contribute to strengthening the cybersecurity of the entire internet.
Our autonomous system and BGP routing ensure that traffic is automatically rerouted to alternative core networks without any downtime for customer servers. Data transfers are unlimited and always take the most efficient path to minimise latency and avoid delays.
