This maintenance operation does not change any customer-specified values such as VPC config, KMS encryption, model, instance type, or instance count.</p> </li> <li> <p> <code>RollingBack</code>: Endpoint fails to scale up or down or change its variant weight and is in the process of rolling back to its previous configuration. Once the rollback completes, endpoint returns to an <code>InService</code> status. This transitional status only applies to an endpoint that has autoscaling enabled and is undergoing variant weight or capacity changes as part of an <a href="https://docs.aws.amazon.com/sagemaker/latest/APIReference/API_UpdateEndpointWeightsAndCapacities.html">UpdateEndpointWeightsAndCapacities</a> call or when the <a href="https://docs.aws.amazon.com/sagemaker/latest/APIReference/API_UpdateEndpointWeightsAndCapacities.html">UpdateEndpointWeightsAndCapacities</a> operation is called explicitly.</p> </li> <li> <p> <code>InService</code>: Endpoint is available to process incoming requests.</p> </li> <li> <p> <code>Deleting</code>: <a href="https://docs.aws.amazon.com/sagemaker/latest/APIReference/API_DeleteEndpoint.html">DeleteEndpoint</a> is executing.</p> </li> <li> <p> <code>Failed</code>: Endpoint could not be created, updated, or re-scaled. Use the <code>FailureReason</code> value returned by <a href="https://docs.aws.amazon.com/sagemaker/latest/APIReference/API_DescribeEndpoint.html">DescribeEndpoint</a> for information about the failure. <a href="https://docs.aws.amazon.com/sagemaker/latest/APIReference/API_DeleteEndpoint.html">DeleteEndpoint</a> is the only operation that can be performed on a failed endpoint.</p> </li> </ul>
