When AWS Broke the Internet: What Really Happened and How to Prepare
November 4, 2025
When half the internet went offline due to a single DNS misconfiguration in AWS’s US East 1 region, it exposed a critical reality: even the world’s most sophisticated cloud infrastructure can fail in unexpected ways. In this episode of SaaS That App: Building B2B Web Applications, Daniel Cannon, Chief Innovation Officer at Delta Systems, joins hosts Aaron Marchbanks and Justin Edwards to break down exactly what happened during the outage, why it cascaded across Netflix, Spotify, and countless other services, and what it means for how you should architect your own systems.
This podcast is brought to you by Delta Systems, your one-stop shop for front-end, back-end, and full-stack software development. At Delta, Justin and Aaron share the same philosophy when it comes to clients: they treat people like colleagues, not just customers. Maybe that’s why Delta typically spends years working with the same companies: how many software engineering firms can you say that about? So, if you’ve got a SaaS project in mind but have no idea where to start, come and get a free scope and estimate from Delta Systems on their website.
Got a burning idea for an episode, or a SaaS question you absolutely must know the answer to? Leave us a voice memo at SaasThatApp.
