Some of the world's biggest apps and websites appear to have stopped working.

Roblox, Snapchat, Fortnite, Canva and Duolingo are among the services that are down, according to website DownDetector.

The problems appear to stem from an issue at Amazon Web Services (AWS), which provides infrastructure for many major websites and apps.

"We can confirm increased error rates and latencies for multiple AWS services in the US-East-1 region," the company said in a statement.

"We are actively engaged and working to both mitigate the issue and understood the root cause.

"We will provide an update in 45 minutes, or sooner if we have additional information to share."

Amazon Web Services is one of the most popular providers of cloud services in the world.
