Many major websites, including Amazon, went dark

A widespread Amazon Web Services (AWS) outage on Monday, Oct. 20, 2025, knocked dozens of major sites and apps offline worldwide, from Amazon and Prime Video to Snapchat, Roblox, and financial platforms.

AWS said the incident centered on its US East (Northern Virginia) region, with core services showing significant signs of recovery by early morning U.S. time.

The disruption reignited concerns about the worlds dependence on a handful of cloud providers as ripple effects hit banks, telecoms, airlines, and government portals.
A major outage at Amazon Web Services (AWS) early Monday spilled across the internet, temporarily breaking access to Amazons own storefront and Prime Video, along with widely used apps including Snapchat, Signal, Roblox, Fortnite, Zoom, and Slack.
Impact spilled into finance (Coinbase, Robinhood, Venmo), transportation and telecom (major U.S. carriers; some airline systems), and connected-home tools such as Alexa and Ring.
AWS status communications and outside monitoring pointed to problems concentrated in the companys U.S. East Coast hub, commonly known as US-EAST-1 in Northern Virginia. The Guardian reported DynamoDB, AWSs managed NoSQL database, was among services experiencing degraded performance, a pattern that can ripple across any customer application relying on it.
How the outage unfolded
Reports began rolling in around the start of the U.K. workday (about 8 a.m. BST), with spikes in error rates and latency noted by AWS and third-party trackers. By 5:27 a.m. ET AWS said it was observing significant signs of recovery, and by shortly after 6:00 a.m. ET most affected services were reporting improvementthough some customers continued working through backlogs.
The number of impacted services spanned consumer, enterprise, and public-sector platforms. Games including Fortnite and Roblox, social and messaging apps like Snapchat and Signal, and Amazons own Alexa and Prime Video were among the most visible outages.
Financial services, major U.K. institutions (HMRC), and even market-data providers saw disruption, underscoring AWSs central role in the digital economy.
Why this matters
Cybersecurity and internet-governance experts emphasized that Mondays incident, while apparently an IT failure rather than an attack, highlights systemic risk from concentration in a few hyperscale clouds.
When a core database or identity service hiccups in a dominant region, the blast radius can leap continents and sectors within minutes. Calls for diversified architectures, multi-region resilience, and contingency plans are likely to intensify following this event.
Mondays outage is one of the broadest internet disruptions since the 2024 CrowdStrike incident that crippled systems worldwide. It will add pressure on cloud customers and regulators alike to stress-test failover strategies, decouple critical functions where feasible, and improve transparency around dependencies many end users never see until everything stops.
"Incidents like this show how much of our daily life now depends on a few big tech providers. When one of them has a problem, it can bring down internet access for millions. The problem is centralisation," saidRobJardin, chief digital officer atcybersecurityexpertsNymVP
The same centralization of internet service provisions in private hands is what enables governments to command internet shutdowns for political reasons, blocking access to information for entire countries. And for ordinary internet users, it means vulnerable points of failure for hackers, data leaks, and impacting technical breakdowns like we are seeing today," Jardin said in an email to ConsumerAffairs.
