Amazon Web Services (AWS) says human error caused the cloud storage system outage, which lasted several hours and affected thousands of customers earlier this week.
Amazon’s Simple Storage Service (S3), which provides backend support for websites, applications and other cloud services, ran into technical difficulties on the morning of Tuesday 28 February in the US, returning error messages to those trying to use it.
The cloud service giant revealed the cause in a post-mortem-style blog post, and explained the issue can be traced back to some exploratory work its engineers were doing to establish why the S3 billing system was performing so slowly.
