Case Study: NHS Choices achieves real-time infrastructure visibility and faster troubleshooting with Splunk Enterprise

NHS Choices Improves Visibility Into Infrastructure to Deliver Critical Online Services

NHS Choices, the UK’s largest healthcare website—serving about 48 million visits a month and hosting 20,000+ articles—struggled to gain visibility into a complex, multi-stack infrastructure. Reliance on external availability monitoring and limited log insight made troubleshooting slow, prevented effective analysis of traffic spikes, and left reporting capabilities inadequate.

By deploying Splunk Enterprise to ingest web, firewall, event and other machine data, the team created real-time dashboards and alerts that consolidate visibility across the site. This enabled faster root-cause analysis (including post‑incident DDoS reviews), proactive issue detection (e.g., message‑queue alerts), better traffic management during spikes, improved reporting for releases and product owners, and lower overall infrastructure costs.
