Sep 1, 2025September 2025 monthly summary for NHSDigital/nbs-appointments-management-service focusing on delivering business value through reliable availability data, improved visibility, and stronger infrastructure. Key features delivered include a cross-environment Site Status filter to unify site visibility, routing of availability queries to a high-load Function App with an Akamai URL update, and a direct network path from the web app to the Function App to improve reliability and reduce latency. Major bugs fixed include a midnight-edge case in hourly availability retrieval (with added integration tests) and a data extraction fix for booking sources to handle string values correctly, both guarded by tests to prevent regressions. Additional maintenance and infrastructure hygiene improvements (tooling, environment configuration, secret management, and infra fixes) enhanced reliability and developer productivity. Overall impact includes better visibility of availability and site status across environments, more reliable data and connectivity, faster incident resolution, and a scalable foundation for future delivery. Technologies/skills demonstrated include Akamai routing, high-load Function App architecture, direct Function App connectivity, integration testing, Terraform-based infrastructure hygiene, and enhanced observability through tooling and secret management.
