Built for mission-critical applications that cannot afford downtime
Your traffic is routed through completely separate API endpoints, isolated from standard service traffic. No resource contention, no performance impact from other users.
Your service is deployed across multiple geographic regions within the UK with automatic failover. If one region experiences issues, traffic seamlessly routes to healthy regions.
Real-time monitoring of all infrastructure components with instant alerts to our operations team. Issues are detected and resolved before they affect your service.
Ultimate redundancy for maximum reliability
In addition to our primary service with automatic failover, you will receive a separate backup DNS endpoint for ultimate peace of mind. While extremely unlikely, in the event that both our primary service and its automatic failover mechanisms fail, you can manually switch to this backup endpoint within your infrastructure.
Your main API endpoint with built-in automatic failover between UK datacenters.
If primary datacenter fails, traffic automatically routes to secondary (sub-second).
Separate endpoint for manual switchover if both primary systems fail (extremely rare).
Only in the extremely unlikely event that both your primary endpoint AND its automatic failover system fail simultaneously. This provides an additional layer of security for absolute mission-critical applications. Our monitoring team will notify you immediately if such a scenario occurs.
