Amazon.com blamed human error for the disruption in its cloud services that resulted in widespread glitches for its clients from news sites to government services.
An incorrect command led to the removal of a larger set of servers than intended, the company said in a blog post.
The disruption in the company's Simple Storage Service, or Amazon S3, lasted for more than 3-1/2 hours and impacted sending and receiving clients' data.
The company said it will make changes to improve the recovery time of its key S3 subsystems.
