Welcome to this week’s Uptime Sync. This issue opens with Cloudflare Radar's 2025 year-in-review showing internet traffic patterns and attack trends across the globe, a breakdown of the database types that still matter in production workloads, how Netflix relies on Temporal to orchestrate cloud workflows at scale, Pinterest's war story debugging a one-in-a-million failure during their Kubernetes migration, and a detailed postmortem of what went wrong when an AI agent broke loose in production.
On the tutorial front, you'll migrate from Ingress NGINX to Gateway on DigitalOcean with zero downtime, build a highly concurrent in-memory counter in Go the Grab way, walk through exactly what happens when Linux boots from power-on to login prompt, wire up ChatGPT apps using Supabase Edge Functions and MCP, and host Postgres with geo-lookup data using GeoLite2 on Railway.
To wrap things up, this week's projects bring you a self-hosted AI coding assistant that runs on-prem like Copilot but without the external dependency, an extensible Kubernetes dashboard for visibility and Helm management in one clean UI, OWASP's deliberately vulnerable WebGoat app for practicing real security exploits, SigNoz for unified logging-metrics-traces in a single pane, and Trivy: the versatile scanner that hunts vulnerabilities across containers, filesystems, and config files.

Projects of the week
A self-hosted AI coding assistant, offering an open-source and on-premises alternative to GitHub Copilot. It boasts several key features:
An extensible Kubernetes Dashboard provides clear visibility into your Kubernetes clusters and streamlines Helm app management through a single, intuitive interface.
A deliberately insecure web application maintained by OWASP designed to teach web application security lessons.
A tool to track all your logs, metrics, and traces in one place. Monitor your application, spot issues before they occur and troubleshoot downtime quickly with rich context.
A comprehensive and versatile security scanner. Scanners that look for security issues, and targets where it can find those issues.
Until next time,
