Amazon Web Services was named as the cause of the problem by the chief executive of AI company Perplexity.
Aravind Srinivas posted on X saying: “Perplexity is down right now. The root cause is an AWS issue. We’re working on resolving it.”
AWS describes itself as “the world’s most comprehensive” cloud service.
It offers companies a virtual backbone, giving them access to servers, databases and storage without having to build their own infrastructure.
Millions of businesses are thought to use AWS, so when something goes wrong, it can have a huge impact.
