Service is operating normally: [RESOLVED] EBS connectivity issues in a single Availability Zone
7:32 PM PDT We are currently investigating connectivity issues between EC2 instances and a small set of EBS volumes in a single Availability Zone in the US-EAST-1 Region. Some API calls to create new EBS volumes and snapshots in this Availability Zone will return errors during this issue. Additionally, a small number of existing EBS volumes in that Availability Zone are currently experiencing connectivity issues.
8:01 PM PDT We have identified the root cause of the issue and are deploying a fix. Connectivity has now been restored to most of the affected EBS volumes.
9:11 PM PDT We are continuing to work to restore connectivity to all EBS volumes. Connectivity has now been restored to all but a few remaining volumes.
10:44 PM PDT We have deployed the fix and connectivity is now restored for all EBS volumes. Error rates around API calls to create new EBS volumes and snapshots have now dropped and the service is operating normally.
[RESOLVED] Instance Connectivity
10:33 AM PDT A very small number of instances in a single Availability Zone in US-EAST-1 Region experienced a loss of connectivity from 9:10 AM PDT to 9:55 AM PDT. All connectivity has been restored.
