Service impact: Connectivity Issues - AWS Outage

Summary

We continue to see significant signs of recovery as a result of our mitigation efforts for the connectivity issues impacting multiple AWS services in the US-WEST-2 Region. We have identified the root cause as an issue with a networking device responsible for network routing from the Region to the Seattle Metro. Engineers have finished all mitigation work. As routes continue to be restored, customers should see a continued reduction in error rates and timeouts when connecting to affected services
