A sweeping global outage triggered by Amazon Web Services (AWS) knocked out many major websites and apps early on October 20, 2025, affecting platforms such as Snapchat, Roblox, Venmo, and online banking services across the UK.
The root cause was traced to DNS and database issues in AWS’s US-East-1 region, underscoring how much of the internet depends on a few providers. Experts say this incident is a stark reminder of how fragile global digital infrastructure can be.
