The Internet Just Had Its Worst Nightmare: Microsoft Azure AND AWS Went Down Simultaneously
On October 29, 2025, the internet experienced what tech experts are calling a "perfect storm" outage. Both Microsoft Azure and Amazon Web Services (AWS) went down simultaneously around 9 a.m. Pacific time (12:00 PM ET), creating a cascading failure that knocked out massive chunks of the internet at once.
Major AWS Outage Takes Down 500+ Companies Including Fortnite, Snapchat, Canva, and Alexa
On October 20, 2025, a DNS resolution failure in AWS US-EAST-1 took down 72 services and affected over 500 companies including Fortnite, Snapchat, Canva, and Alexa. The outage lasted approximately 3 hours, generating over 4 million reports on Downdetector within the first two hours. AWS identified the root cause at 2:01 AM PDT and deployed multiple mitigation paths, achieving full recovery by 3:03 AM. The incident cascaded globally because US-EAST-1 serves as a backend for AWS global services, meaning a single DNS failure spread across the entire ecosystem. The outage revealed that many companies aren't adequately protected by multi-region redundancy since they still depend on US-EAST-1 for critical global services.

As someone who spends most hours diving into binary exploitation and web security, I couldn't afford to spend months wrestling with frontend frameworks.
