If you’re uploading over a spotty network, use multipart uploading to increase resiliency to network errors by avoiding upload restarts. When using multipart uploading, you need to retry uploading only parts that are interrupted during the upload. You don’t need to restart uploading your object from the beginning.
The question did not specify whether a multipart uploading was in process. If it’s a single upload operation, then the upload must restart from the beginning.
