Resumo
Between 11:27 AM and 12:20 PM PST we experienced substantial error rates for S3 PUT/GET requests in EU-CENTRAL-2 Region. Engineers were engaged immediately based on automated alarming. We identified the root cause as an issue with a subsystem responsible for assembling objects bytes in storage. At 12:04 PM PST, we implemented mitigations and began observing early signs of recovery for S3. Error rates continued to improve, and other AWS Services continued to recover until 12:50 PM PST when we observed full recovery. We continue to work toward backfilling Cloudwatch logs, and expect that to continue over the next couple hours. We recommend customers retry any failed requests. The issue has been resolved and all services are operating normally.
