A widespread internet disruption on Monday morning affected several major online services, including Amazon’s AWS cloud platform, Robinhood, Snapchat, and the AI search platform Perplexity, according to the monitoring site Downdetector.

Perplexity’s CEO said the outage stemmed from an issue with Amazon Web Services (AWS), which also impacted Amazon.com, Prime Video, and Alexa.

In addition, users reported problems accessing PayPal’s Venmo service during the incident.
