On Mon, Oct 20, 2025, Amazon Web Services (AWS) experienced a significant outage impacting numerous websites and applications globally. The disruption affected various sectors, including banking, airlines, smart home devices, and gaming platforms, highlighting the reliance on cloud infrastructure.
The outage began around 07:11 GMT due to issues at an AWS data center in Virginia. The problem originated from a technical update to the API of DynamoDB, a key cloud database service. This update led to errors affecting the Domain Name System (DNS), which helps applications locate server addresses.
The DNS issue prevented apps from accessing the IP address for DynamoDB's API, resulting in service failures across 113 AWS services. AWS reported a return to normal operations by 10:11 GMT, with a backlog of messages to process.
The outage affected numerous services, including Snapchat, Pinterest, Apple TV, WhatsApp, Signal, Zoom, Slack, and gaming services like Roblox, Fortnite, and Xbox. Financial apps such as Venmo, Ring doorbells, Alexa speakers, and the Amazon website were also impacted.

Additionally, the outage affected the language app Duolingo, creative tool Canva, and media organizations like the Associated Press, The New York Times, and The Wall Street Journal. Several banks, cryptocurrency exchange Coinbase, and airlines like Delta and United reported issues.
AWS acknowledged the outage and reported that engineers were immediately engaged to resolve the problem. Efforts were made to accelerate recovery, and AWS indicated that the main issue was resolved, although some users experienced minor delays. A detailed post-event summary will be published by AWS.
Cloud services refer to storing and accessing data or applications over the internet rather than on local devices. AWS provides companies with computing power and storage, enabling them to operate websites, apps, and online services. DynamoDB, a vital AWS service, stores critical company data, such as customer records.
AWS is the largest cloud service provider globally, and while cloud outages are not uncommon, their impact is more pronounced due to the extensive reliance on these services.
The AWS outage demonstrated the widespread dependency on cloud infrastructure and the potential challenges when disruptions occur. Despite the incident, AWS remains a dominant player in the cloud service market, and its users are unlikely to seek alternatives immediately.
