Amazon EBS will be undergoing system maintenance on February 16th, from 1:30 AM to 1:45 AM PST. During the maintenance customers may notice an increase in 500 errors for requests to create, attach, detach and delete volumes. The creation of snapshots from volumes will also temporarily return a 500 error code. All other requests to the Amazon EC2 API will continue to be processed normally.
The issue has been resolved. Requests to describe newly created resources was delayed between 9:06AM PST and 9:40AM PST. The service is now operating normally.
We are investigating delays in newly created resources being immediately available for describe calls in the US-EAST-1 Region. All other requests to the API are functioning normally. Running instances are not impacted.
API error rates in the US-EAST-1 Region have now recovered. The service is operating normally.
We can confirm that we are experiencing elevated error rates for EC2 API calls in US-EAST-1 Region. There is no impact to running instances. We are continuing to investigate this issue.
We are investigating elevated errors in the US-EAST-1 Region.
We have identified a router that was causing brief connectivity issues (two ten minute periods) for a very small set of instances in a single Availability Zone in the US-EAST-1 Region. We have removed the problematic router and the service is operating normally.
We are investigating intermittent connectivity issues for some instances in a single US-EAST-1 availability zone.
The issue has been resolved. Newly created resources are now immediately available for describe calls. The service has been functioning normally for the last 25 minutes (since 2:45am PST).
