Case Study: MIS Systems Engineering achieves 99.999+% uptime for UK Ambulance Services with Stratus Technologies' ftServer

Guaranteeing Uptime All The Time For UK Ambulance Services

MIS Systems Engineering, the maker of the C3 NEXUS command-and-dispatch system used by about 75% of UK and Ireland ambulance services, faced rising emergency call volumes and tougher government targets (75% of priority-one calls on scene within eight minutes) after Trust consolidation. Their existing Intel clustering couldn’t guarantee zero downtime or protect in‑memory data, so they needed an ultra‑high‑availability, budget‑friendly solution that didn’t require specialist retraining.

MIS selected Stratus ftServer — a fully fault‑tolerant, Intel‑based platform with automated uptime monitoring that integrated with EISEC, AVLS/GPS and embedded GIS — and deployed it without code changes. The result was a 99.999+% availability promise, faster and more reliable C3 NEXUS performance (top-tier EOC handling times), reduced support complexity and costs, and capacity for future expansion.
