Amazon Web Services, the cloud-computing backbone for scores of websites and apps, had problems that interrupted service to many customers Tuesday.
The problems originated in Amazon Web Services’ S3 data storage system, the company said.
“We are working hard at repairing S3, believe we understand root cause, and are working on implementing what we believe will remediate the issue,” the company wrote on its status website.
Sites including Quora and Trello were brought down by the outage.
“One of those moments when you realize just how much of the world runs on AWS,”tweeted Stella Garber, the Chicago-based vice president of marketing at Trello.
