Millions of users across the world were hit by widespread internet disruptions today after a major Amazon Web Services (AWS) outage took down large portions of the web, including household names such as Snapchat, Fortnite, Duolingo, Signal, and even parts of Amazon itself.
The problems began early on Monday morning (UK time), when AWS reported “increased error rates and latencies” in its US-East-1 (Northern Virginia) data centre region, one of the company’s most critical cloud hubs.
Within minutes, apps and websites that rely on AWS began to crash or slow down. By mid-morning, the issue had escalated into a global outage, affecting banks, streaming services, airlines, government platforms, and smart-home devices like Amazon Alexa and Ring.
What Went Wrong
AWS engineers later confirmed that the disruption stemmed from database and DNS issues, causing internal systems to fail and requests to time out. While rumours of a cyber-attack briefly circulated on social media, cybersecurity experts and Amazon itself have said it appears to be an internal technical fault, not a hack.
The outage mainly hit the US-East-1 region, but because so many global systems use that area as their “primary” connection point, the failure spread like dominoes.
By around 10:30 a.m. UK time, AWS reported that most services were “showing signs of recovery,” and by 11:00 a.m. the majority of systems were back online. Still, millions of users experienced hours of downtime or degraded service.
Who Was Affected
The list of affected platforms reads like a who’s who of the modern internet:
- Snapchat, Fortnite, Duolingo, Roblox, and Wordle users all reported login failures or server errors.
- Financial apps such as Venmo, Coinbase, and Robinhood temporarily went dark.
- In the UK, Lloyds Bank, Bank of Scotland, and even parts of HMRC were affected.
- Alexa voice services, Ring doorbells, and parts of Amazon.com’s own retail infrastructure were also hit.
Even airlines and telecom providers including AT&T and Verizon reported intermittent issues, underlining how deeply AWS is embedded in global connectivity.
Why It Matters
AWS isn’t just another web host, it’s the backbone of much of the modern internet. From entertainment and banking to healthcare and logistics, thousands of services depend on Amazon’s cloud to function.
When one AWS region goes down, the consequences can be global, as today’s incident showed. It highlights what experts call “concentration risk” , the vulnerability that comes from so many companies relying on the same cloud provider or region.
Digital rights advocates and regulators have already raised questions about resilience and diversification in the cloud sector, especially when public services such as HMRC are affected.
Lessons for Businesses
Outages like this serve as a stark reminder to organisations that resilience must be built in from the start.
Key takeaways include:
- Use multiple regions – Don’t rely solely on US-East-1 or any single zone.
- Plan for failure – Architect systems that can degrade gracefully instead of collapsing outright.
- Monitor dependencies – Even if you don’t host with AWS directly, your suppliers or vendors might.
- Communicate transparently – Let users know when an upstream provider is to blame; silence erodes trust.
- Review disaster-recovery plans – AWS will release a post-event summary (PES); use it to stress-test your own setup.
Recovery and Outlook
As of this afternoon, AWS confirmed that all major services are operational again and that engineers are preparing a full post-incident report detailing the technical root cause.
Businesses are now clearing backlogs and re-syncing data from the downtime, while analysts predict renewed scrutiny of Amazon’s cloud dominance and the reliability of critical infrastructure.
For users, today’s outage was an inconvenient reminder that the cloud isn’t invincible, and that even the internet’s biggest players can have bad days.
