March 2025 monthly summary for derailed/cilium: Delivered a network bandwidth testing feature for the Cilium CLI connectivity tests. Added a --bandwidth flag, deploys client and server pods with explicit egress/ingress bandwidth limits, and validates throughput to enforce limits. Expanded test coverage for bandwidth QoS, reducing regression risk for performance-sensitive workloads. Commit 3c6221c78a1904b192083a538d1489d2646c45b0 (feat(connectivity): add network bandwidth management test). Impact: improves reliability for multi-tenant deployments and SLAs. Technologies: Kubernetes, Cilium CLI, test harness, throughput measurement. Business value: ensures bandwidth guarantees and early detection of regressions; supports customers' performance expectations and operational stability.

January 2025 monthly delivery focused on stability and performance: rolled back an incompatible webhook migration and implemented robust in-service certificate management; introduced eBPF-based bandwidth control for Cilium with ingress/egress rate limiting; updated CLI/docs and token management to improve usability and observability.

December 2024 monthly summary for rancher/cilium focused on delivering a new observability control for the gops diagnostic agent and strengthening operator experience through updated documentation. The month centered on feature delivery and ensuring deployment flexibility, with no critical regressions addressed.
