November 2025 highlights two repos delivering performance improvements, reliability fixes, and governance enhancements across frontend infrastructure and platform configuration. In alphagov/govuk-fastly, we delivered rate limiting improvements, removed legacy Terraformed CDN limits, fixed rate limiting reliability with correct VCL error handling, and added TLS Subscriptions Management to configure and import TLS subscriptions. In alphagov/govuk-infrastructure, we adopted Pkl as the configuration language (ADR0022) for maintainability and type safety, and extended GOV.UK Mirror with Athena-based popularity verification, including IAM policy updates for S3, Athena, and Glue to enable data-driven validation against live site data. Major bug fix addressed VCL syntax for rate-limiting error handling to ensure proper error responses. These changes reduce operational risk, improve cache efficiency, enable secure TLS management, and empower data-driven decisions.

October 2025 performance summary for alphagov/govuk-infrastructure: Modernized CI/CD and Kubernetes resource management through ADR-driven architectural decisions. Delivered a hybrid Concourse-based CI/CD model with per-environment pipelines and a central artifact build hub, and initiated Crossplane-based resource abstraction to replace Helm-centric patterns. Implemented infrastructure manifest versioning to improve reproducibility and auditability. Traceability to ADRs (ADR 019: Restructure CI/CD; ADR 0020: Use Crossplane for Abstraction) with commits b6e20f111e10b1f254dca6b5171a400a1856bf1c and d204783c56155d47cce6b3ca39b028a3c828d2b4. Major bugs fixed: none reported this month. Overall impact: faster, more predictable releases and transformed platform governance.

September 2025 performance summary for alphagov/govuk-developer-docs: Delivered critical documentation updates for GOV.UK publishing infrastructure and GitHub Actions guidance. Focused on reducing operational risk by clarifying DNS records location, CloudFront failover workflow, and pinning actions to specific versions via commit SHAs. Resulting changes improve onboarding, accuracy of infrastructure guidance, and cross-repo collaboration.

August 2025: Infrastructure and data services modernization focused on reliability, security, and upgrade readiness. Implemented end-to-end Content Data Admin PostgreSQL upgrades (13 in integration and 14 in integration) with Terraform state imports, parameter groups, replication, and cleanup/rollback. Enabled per-database major PostgreSQL upgrades (including publisher to PostgreSQL 17) and rolled out replication in integration, staging, and production to improve availability and disaster recovery. Adopted ADR0018 to standardize CI/CD with Concourse. Hardened CI/CD security and reproducibility by globally pinning GitHub Actions to specific commit hashes across all repos, aligned NodeJS LTS in CI, and refreshed tooling. Documentation improvements to replace generic links with meaningful text. These efforts deliver smoother upgrade paths, reduced operational risk, and more predictable deployments across environments.
