    HTTP Early Hints (status code 103) is a powerful feature that allows servers to send hints about critical resources before the main response is ready. This can significantly improve loading performance by letting browsers preload key assets earlier. In this article, we'll implement Early Hints using Cloudflare Workers and R2 storage for a static site.

    Setting up a highly available Kubernetes cluster can be challenging, especially when dealing with nodes across different network topologies. This blog walks through setting up a K3s cluster from scratch, no IaC, with both public and private nodes, using Tailscale for secure networking, and handling common pitfalls along the way.

    Let's explore how to build a resilient K3s cluster that can handle node failures while maintaining secure communication between nodes.
