TL;DR

After a brutal 24-hour outage on October 19, 2025, AWS finally published its root cause analysis 10 days later, pinpointing a DNS failure in Dynamo that cascaded into EC2 and Network Load Balancer errors. If you want the deep dive, timestamps guide you to the DNS breakdown (5:30), EC2 issues (13:41) and NLB hiccups (16:16).

Along the way, the video host plugs a suite of backend dev courses—covering OS fundamentals, Node.js internals, networking, databases, Python, NGINX—and even offers a podcast, an Arabic channel, and “members only” content for anyone keen to level up while AWS lessons sink in.
