🚀 Major Update: Errloom Just Leveled Up
Errloom is the interactive debugging platform where you dive into recreated production outages from companies like Reddit, GitLab, Discord, AWS, and Cloudflare — but today’s update takes it even further.
What’s New
🔥 Internet-breaking incidents
Tackle legendary failures like Netflix’s Chaos Monkey mayhem, Knight Capital’s $440M meltdown, and the Fastly CDN outage that took down half the web.
🎬 Video-powered onboarding
Every scenario now starts with a quick visual overview so you know exactly what you’re about to investigate.
📊 Smarter difficulty progression
Beginner, intermediate, and expert tiers so you can climb the debugging ladder at your own pace.
🍎 Polished new UI
A clean glassmorphism interface with a bento-style grid makes each scenario feel like a mini adventure.
Why This Matters
Most debugging tutorials are toy problems. Real production failures involve distributed systems, cascading outages, missing data, and pressure.
Errloom closes that gap by turning famous real-world incidents into hands-on, browser-based practice.
Free. Open source. Runs entirely in your browser.
No setup. No sign-up. Just pure, immersive debugging.
