Hussein Nasser: We now know why the DNS failed

AWS’s DNS went belly-up on October 19, 2025, knocking services offline for over 24 hours. Ten days later AWS dropped their root cause analysis, laying out exactly how Dynamo’s DNS lost its mojo (5:30 in the video), EC2 threw errors (13:41), and the Network Load Balancer stumbled (16:16). You can catch the quick 0:00 summary or dive deep via the official RCA linked in the description.

Beyond that, host Hussein peppers the video notes with a treasure trove of backend goodies—courses on operating systems, Node.js, networking, databases, NGINX, Python, plus his YouTube channels, podcast, and even a “buy me a coffee” link for those who want to keep the content coming.
