In order to increase the ops awareness of the process, it'd be good if we could document on Wikitech the technical process of server-side uploading tasks. There's a bit of explaining at https://commons.wikimedia.org/wiki/Help:Server-side_upload and at https://wikitech.wikimedia.org/wiki/Uploading_large_files However recently there have been some technical limitations with server-side uploading as well, such as those in T191572. Should we expand that a bit?
