AWS Power-related Outage in Older Data Center Ends, Once Again Hits Single Center Customers

From the AWS Service Health Dashboard:

9:32 AM PDT Connectivity has been restored to the affected subset of EC2 instances and EBS volumes in the single Availability Zone in the US-EAST-1 region. New instance launches are completing normally. Some of the affected EBS volumes are still re-mirroring causing increased IO latency for those volumes.

As happened earlier this month the failure was apparently triggered by power systems failures. The US-EAST-1 data center in Virginia is Amazon’s oldest.

As in the past, the outage hurt customers relying on a single center.
