Several high-profile websites and service sites, such as Quora, a Q&A forum, and Trello, were shut down offline by a failure in Amazon Web Services (AWS).
AWS allows companies to rent cloud servers to host data on the Internet without having to invest in their own infrastructure.
On February 28, sites that help people monitor productivity crashed.
A few hours later, Amazon said it had fixed the problem.
This did not make public the reason for the interruption.
In addition to the sites that crashed, other services, such as the Slack Workplace Collaboration Tool, also lost some key features.
In particular, this was affected by S3 of AWS – which means Simple Storage Service.
To varying degrees, it serves about 150,000 sites and services worldwide, mostly in the United States.
AWS is used by some of the most recognizable and powerful names on the web, including Netflix, Spotify and Airbnb. Although none of these services are offline on February 28, users report performance issues and latency.
US government departments such as the Securities and Exchange Commission (SEC) are also affected.
Stay is a critical issue for any cloud service. Amazon is competing with Google, Microsoft and others for what is an increasingly lucrative business for web giants.
