Behind the Scenes: How We Ensure 99.9% Uptime
In today's always-on digital world, uptime plays a critical role in how modern services operate. For many of our customers, downtime means lost transactions, broken APIs, or unavailable internal tools.
In this article, we'll take you behind the scenes of how Serverspace builds the reliability that powers your systems with 99.9% uptime.
A Clear and Transparent SLA You Can Rely On
At the heart of our uptime promise is the Service Level Agreement (SLA) — a legally binding commitment that defines uptime, availability metrics, and what compensation you receive if targets aren't met. Serverspace guarantees that rented virtual machines have a target availability of 99.9%, with uptime measured around the clock. In cases where availability drops below the SLA target, customers are eligible for tiered financial compensation based on how far the outage deviates from the SLA threshold.
This approach ensures uptime commitments are backed by formal obligations and directly reflected in how we operate.
We use the SLA as a practical benchmark for engineering processes, operational decisions, and support response standards.

Geo-Distributed, High-Reliability Data Centers
Where your infrastructure runs has a direct impact on overall uptime.
Serverspace operates multiple data centers around the world, spanning North America, Europe, Asia, and South America. Locations include New Jersey (USA), Amsterdam (Netherlands), Toronto (Canada), Almaty (Kazakhstan), São Paulo (Brazil), and Dubai (UAE).
This geographic distribution allows customers to place workloads closer to end users or build multi-region architectures within the Serverspace ecosystem.
Each facility is engineered to deliver:
- Fault-tolerant architecture with fully independent power systems to remove single points of failure.
- Advanced security systems that safeguard equipment from internal and external threats.
- Proximity to major network hubs for high-performance connectivity and low latency.
- Geo-redundancy enables services to run closer to users while maintaining consistent availability.

Enterprise-Grade Hardware and Network Redundancy
High availability depends heavily on how hardware and networking components are designed and deployed.
Serverspace relies on proven enterprise hardware — including redundant Cisco networking equipment and resilient storage systems — chosen for stability and predictable performance.
This includes:
- High-performance Cisco ASR and Nexus switches for resilient networking.
- Redundant power and cooling to ensure stability in all conditions.
- Multiple storage tiers capable of delivering sustained I/O performance.
- Together, these components provide a stable baseline for continuous infrastructure operation.
Virtualization Platforms Built for High Availability
Serverspace provides infrastructure services based on enterprise virtualization technologies like VMware and vStack. These platforms are designed to support high-availability scenarios:
- VMware ESXi with DRS/HA automatically redistributes workloads and restarts virtual machines when hardware issues arise.
- vStack delivers a lightweight hypervisor optimized for performance while maintaining reliability.
- As a result, hardware failures or maintenance events cause minimal disruption to running services.
For customers, this results in fewer manual interventions and faster recovery during infrastructure-level incidents.
Proactive Monitoring and Support
Even the most robust infrastructure requires continuous monitoring and experienced teams to maintain uptime.
Our monitoring systems track infrastructure health continuously, while on-call engineers are alerted automatically if thresholds are exceeded — often before customers notice any impact or before an issue escalates into an outage.
Built-In Transparency and Tools
Serverspace provides users with a rich control panel and API tools that make it easy to manage and monitor uptime:
| Feature | Description |
|---|---|
| Real-time metrics and logs | Monitor resource utilization, performance indicators, and system logs in real time to quickly detect anomalies. |
| Global DNS and networking tools | Use geo-distributed DNS and networking features to improve availability, reduce latency, and enhance fault tolerance. |
| Automated provisioning and scaling | Deploy and scale infrastructure automatically to handle traffic spikes and ensure consistent uptime. |
| API & CLI for DevOps | Integrate Serverspace infrastructure into CI/CD pipelines using API and CLI tools for full automation and control. |
