Amazon.com Inc. has sent a cease-and-desist letter to Perplexity AI Inc. demanding that the artificial intelligence search startup stop allowing its AI browser agent, Comet, to make purchases online for users.

OpenAI signs a $38 billion deal with Amazon Web Services, shifting away from Microsoft as the exclusive cloud provider.

Perplexity AI said on Tuesday it has received a legal threat from Amazon.com demanding that the startup block the AI agent on its Comet browser from shopping on the e-commerce giant's platform on a user's behalf.

Experts say the incident revealed what can happen when a such a broad spectrum of companies rely on singular cloud provider.

Amazon posted higher fiscal third quarter profit and sales compared with a year ago, fueled by accelerating growth in its cloud computing business and strong spending by its customers looking for low prices at a time when inflation is resurging.

Amazon Web Services outage is causing major disruptions around the world, including platforms ranging from Disney+ and Alexa to Venmo and Roblox.

An Amazon Web Services outage impacting Amazon's own services and as well as apps around the world wasn't resolved until Monday evening.`

AWS said in a statement that the issue has been mostly resolved, and it would “continue to work toward full resolution."

Amazon Web Services experienced a significant outage on Monday morning, taking Snapchat, Roblox and several major banks offline.
