Amazon Web Services (AWS) has fully recovered from a major global outage caused by DNS issues

Amazon Web Services (AWS) has fully recovered from a major global outage caused by DNS issues, restoring access to key platforms like Snapchat, Zoom, and Prime Video.

Here’s a detailed breakdown of what happened:

🛑 What Caused the Outage?

– The outage began around 3 a.m. EDT on October 20, 2025, affecting the US-East-1 region, one of AWS’s most critical zones.
– The root cause was a DNS resolution failure—a disruption in the system that translates domain names into IP addresses. This impacted DynamoDB service endpoints, which many apps rely on.

🌐 Who Was Affected?

– The outage disrupted major websites and apps including:
– Snapchat, Fortnite, Ring, Roblox, Coinbase, Signal
– Amazon services like Prime Video, Alexa, and Ring
– Even banks, government services, and e-commerce platforms experienced downtime due to their reliance on AWS infrastructure.

🛠️ Recovery Timeline

– AWS began mitigation efforts shortly after identifying the DNS issue.
– By 2:24 a.m. PDT, the core issue was resolved, but some internal subsystems remained impaired.
– AWS temporarily throttled EC2 instance launches to stabilize recovery.
– By 12:28 p.m. PDT, most services were back online and functioning normally.

🔍 Broader Implications

– The incident highlights the vulnerability of global cloud infrastructure when a single region experiences failure.
– Experts are urging businesses to re-evaluate their cloud architecture to avoid single points of failure.
