Increased API Error Rates and Latency

8:36 AM PDT We are investigating increased API error rates and latency in the US-EAST-1 Region. This will impact customers' ability to make calls to Parameter Store.

9:29 AM PDT We can confirm increased API error rates and latencies for the Systems Manager Parameter Store in the US-EAST-1 Region. Customers using the Parameter Store for the storage of data may be affected by the event as they are unable to retrieve the data. We have identified the subsystem where the errors are occurring and are working to resolve the issue. At this stage, we expect recovery to take more than an hour but will keep you updated on our progress.

9:50 AM PDT We continue to work on the issue causing increased API error rates and latencies for the Systems Manager Parameter Store in the US-EAST-1 Region. Customers using the Parameter Store for the storage of configurations may be affected by the event as they are unable to retrieve the data. Customers invoking Lambda functions that use Environment Variables will also experience increased error rates and latencies. The subsystem responsible for the Parameter Store is experiencing resource contention, which is leading to the increased error rates and latencies. We continue to work toward the resolving the issue, but do not have an ETA on recovery at this stage. We will keep you updated on our progress.

10:33 AM PDT We continue to work on the issue causing increased API error rates and latencies for the Systems Manager Parameter Store in the US-EAST-1 Region. Customers using the Parameter Store for the storage of configuration may be affected by the event as they are unable to retrieve the data. We have confirmed that customers using Lambda Environment Variables are not affected by this event, but rather customers that are attempting to access the Parameter Store directly from a Lambda function. Customers can work around the issue by removing the use of the Parameter Store from their code, or look to use some other store, such as DynamoDB. We are making progress towards resolution but continue to see elevated error rates for the affected subsystem. We do not have an ETA on recovery at this stage and will keep you updated on our progress.

11:02 AM PDT We are seeing recovery for the issue causing increased API error rates and latencies for the Systems Manager Parameter Store in the US-EAST-1 Region. Customers using the Parameter Store for the storage of configuration should be seeing recovery at this stage. We continue to monitor the subsystem that was experiencing resource contention, but expect error rates and latencies to remain at normal levels.
