AWS Outage Disrupts Global Services: What Happened on October 20, 2025
Amazon Web Services (AWS), the backbone of many online platforms, experienced a major outage on October 20, 2025, leaving millions of users without access to key services. Starting in the early hours of the morning, the disruption had a global ripple effect, hitting apps, financial platforms, and smart-home devices.
Services Affected Worldwide
The outage began around 3:11 a.m. ET, with AWS confirming elevated error rates and latency in its US-EAST-1 (Northern Virginia) region. This region is one of AWS’s largest and most critical, meaning even a localized issue can cause widespread impact. Within minutes, platforms like Snapchat, Fortnite, Duolingo, and Ring stopped working. Even Alexa devices and Amazon’s retail systems slowed down or froze entirely.
Financial services such as Lloyds Bank in the UK reported access issues. In total, users filed over 6.5 million disruption reports on outage tracking sites. Apps that rely on AWS infrastructure for hosting, databases, or APIs couldn’t process requests.
What Caused the Outage?
AWS cited internal faults related to DNS systems and network load balancers in the affected region. A failure in health-check monitoring triggered a cascade of service errors across various systems, causing several AWS services to fail simultaneously.
While rumors initially swirled about a cyberattack, AWS later clarified there was no evidence of malicious interference. By late morning, the team had restored most services and stabilized performance across affected systems.
The Bigger Picture: Cloud Dependency Risks
This isn’t AWS’s first major incident, but the 2025 outage highlights just how fragile the internet can be when so many services rely on a single provider. Tech analysts have called the event a wake-up call, emphasizing the risk of cloud centralization.
For businesses, it underlined the need for multi-region or multi-cloud redundancy. Relying solely on a single AWS region can be cost-effective, but it leaves companies exposed to outages like this.
