TIER 3 data center
–
guaranteed uptime
We operate a certified TIER 3 data center in the Czech Republic with a minimum guaranteed uptime of 99.982%. Our infrastructure meets the strictest international standards and offers redundant systems with zero overbooking.
At TTC DC2, we also provide optional power configurations that meet TIER IV data center standards. Ensure uninterrupted operation of your critical systems, hosted in the largest and most advanced high availability data center in Central Europe.
Why choose our TIER 3 data center
Why 99% of companies choose TIER 3 data centers
TIER III certification by Uptime Institute ensures true high availability for your systems. Our TIER 3 data center meets all critical requirements: redundant power, cooling, and connectivity in an N+1 configuration, with full support for live maintenance.
For special use cases, TTC DC2 offers power configurations that meet TIER IV data center standards (2N+1). For most companies though, the marginal gain in uptime—from 99.982% to 99.995%—doesn’t justify the significantly higher cost.
Behind the numbers: our certified TIER 3 data center
What does TIER III certification mean in practice?
- Dual 22 kV power feeds from two independent substations
- 9 diesel generators with auto-start in under 30 seconds
- 60,000 liters of diesel in on-site storage tanks
Cooling? We run 8+1 fully independent cooling units in an N+1 configuration.
Each power block has its own dedicated UPS and can be serviced without disrupting operations. Non-IT infrastructure is backed by separate UPS systems. And with zero overbooking, your reserved capacity is always fully guaranteed.
A certified TIER 3 data center is your competitive edge
Why does certification matter? Client auditors require it. Insurers offer lower rates for certified data center infrastructure. And your compliance team can finally relax. We meet ISO 27001, ISO 20000, PCI DSS, and NSA standards for critical infrastructure.
Cutting corners on a data center will cost you more in a year than you’ll save in a decade. Our PUE of 1.34 means cooling costs up to 40% lower than the market average. And with our transparent pricing, you only pay for what you actually use—no hidden fees.

Shaping the data center industry in Central Europe since 2001
When we got started back in 2001, TIER certifications didn’t even exist. But from day one, we built with high availability in mind. Our TIER III certification, awarded in 2015, simply confirmed that we’d been doing it right all along.
Today, 60% of Czech internet traffic flows through our facilities. We’re trusted by global corporations and government institutions alike. After 24 years, we know a TIER 3 data center isn’t just about infrastructure. It’s about partnerships built on trust and transparency.

Frequently asked questions (FAQ)
Is your electricity pricing fixed throughout the year?
No. TTC TELEPORT purchases unregulated electricity based on SPOT market prices. As a result, the price of electricity can change every 15 minutes.
We need to connect to another customer (ISP) within your data center. How quickly can you set up the connection?
For a simple connection (e.g. a two-fiber cable), we can deliver a cross-connect by the next business day. More complex connections (e.g. 24 fibers) are typically completed within 5 business days.
What is the maximum cooling capacity per cabinet?
This depends heavily on the customer’s technology. However, we have experience cooling cabinets with power densities of up to 55 kW.
What happens if there is a power outage in Prague?
Your infrastructure will continue running. We operate two independent power feeds (2× 10 MW) and backup systems in an N+1 configuration. In the event of an outage, UPS systems take over immediately, followed by diesel generators with sufficient fuel for long-term operation.
What certifications support the quality of your services?
We hold the highest certifications in the industry, including ISO 27001 (information security), ISO 9001 (quality management), ISO 20000 (IT service management), and ISO 14001 (environmental management). Our infrastructure meets TIER III standards, with power configurations aligned with TIER IV requirements. We also support PCI-DSS, NIS2, and DORA compliance.
How does your cooling system work? Will our hardware overheat in summer?
We use a controlled cooling system with hot and cold aisle containment. The environment is monitored by more than 7,000 temperature and humidity sensors. The system is fully redundant (N+1), ensuring stable conditions even in case of a failure.
How is the physical security of my hardware ensured?
The entire site is secured and monitored 24/7. Access is controlled via reception and security turnstiles. Facilities are covered by CCTV with up to 90 days of recording, supported by biometric readers and electronic access systems.
