The retail giant’s main U.S. site went offline at approximately 3 p.m. ET on Monday. The cause of the outage remains unclear, but Amazon Web Services (AWS), including EC2, remained up and working on the most part unaffected, according to its status page.

However, after we first published this post, at 3:14 p.m. ET, the AWS Management Console was experiencing elevated error rates across all regions of the world, including North America and Europe. There was also a flagged issue with a North Virginia data center that was quickly resolved.

Affected sites were restored about 25 minutes later, as was the AWS Management Console, though it was still experiencing “elevated error rates” during its recovery. Amazon said it experienced “an increased error rate for CreateTags and DeleteTags APIs in the US-EAST-1 region.”

The cause of the outage is not clear. Interesting that Amazon-owned Audible.com was down as well.
