TL;DR

AWS finally published the root-cause analysis for the massive outage that hit on October 19, 2025—an epic DNS failure in their Dynamo service that spiraled into EC2 and Network Load Balancer errors. In a deep-dive video, Hussein breaks it down with timestamps (0:00 summary, 5:30 DNS disaster, 13:41 EC2 chaos, 16:16 NLB meltdowns) and links to the official RCA.

If you’re hungry for more backend wizardry, Hussein’s packed the description with courses (OS fundamentals, Node.js internals, networking, databases, NGINX, Python), his Medium, YouTube memberships, podcast, affiliates and even a “buy me a coffee” link—basically your one-stop shop for leveling up server-side skills.
