A widespread outage at Amazon Web Services (AWS) early Monday morning disrupted access to several major websites and apps worldwide, including Amazon, Snapchat, Facebook, and key airline and banking systems.
Monitoring site DownDetector reported significant spikes in outage reports from users across the United States, particularly in New York, San Francisco, and Los Angeles. Nearly half of all global reports originated from the U.S. East Coast.
“We have confirmed multiple AWS services experienced network connectivity issues in the US-EAST-1 Region,” AWS said in its most recent status updates.
“We have identified that the issue originated from within the EC2 internal network. We continue to investigate and identify mitigations.”
In the U.S., Delta Air Lines and United Airlines were among the companies hit by service disruptions. Across the Atlantic, customers of major British banks—Lloyds, Bank of Scotland, and Halifax—reported being locked out of their online accounts.
The U.K. government’s tax service, HMRC, and the main government portal, Gov.uk, were also affected.
AWS first detected “increased error rates and latencies” across several services in the early hours of Monday, pinpointing the issue to its US-EAST-1 region in Virginia.
At 4:26 a.m. ET, Amazon confirmed “significant error rates” tied to its DynamoDB database service. By late morning, the company identified the root cause as an “internal subsystem responsible for monitoring the health of our network load balancers.”
To stabilise systems, AWS said it “temporarily throttled some impaired operations such as EC2 instance launches.”
“Engineers traced the disruption to DNS resolution issues—a critical process that connects domain names to their underlying IP addresses,”
Gaming platforms including Fortnite, Roblox, and Clash of Clans saw widespread login failures, while social media services such as Snapchat, Reddit, and Facebook reported connectivity issues. At one point, outage reports for Snapchat alone topped 7,000 globally.
Other affected services included Microsoft365, Zoom, Duolingo, Hinge, Ring, AT&T, and streaming platforms like Hulu and Tidal.
Financial and productivity tools such as Venmo, Coinbase, Slack, and Canva were also hit, underscoring the scale of the disruption.
By 6:01 p.m. ET, AWS confirmed that “all services returned to normal operations.”
The outage once again highlighted the global dependence on Amazon’s cloud infrastructure, which powers large portions of the internet—from consumer apps to critical business and government systems.
Hundreds of websites and apps were reporting outages on Monday morning, causing a massive disruption across the internet.
Here’s a list of websites, apps and services that reported issues, according to the online outage tracker DownDetector.

Earlier in 2024, AWS suffered a seven-hour disruption on July 30,, in its U.S.-East-1 region due to a failure in an internal Amazon Kinesis Data Streams cell.
On February 13, 2025, customers in the Stockholm region experienced elevated error rates and increased latency due to networking issues internal to the region.
AWS holds 37% of the global cloud market share and generated $107.6 billion in revenue in 2024, making disruptions particularly impactful across critical infrastructure sectors worldwide.
