TL;DR
AWS’s October 19, 2025 outage knocked DNS offline for over a day. The newly released RCA shows a cascade of failures—Dynamo losing its DNS, EC2 errors and Network Load Balancer hiccups—led to the global disruption.
The video also drops handy timestamps (Summary at 0:00, Dynamo at 5:30, EC2 at 13:41, NLB at 16:16) and links to the full RCA, plus a ton of frontend/backend courses and tutorials by Hussein Nasser—from Node.js internals and networking to database engineering and NGINX—all packed with coupon codes and extras.
