@james IONOS Support analyzed the situation and comes back with this:
Hello,
Thank you for your patience. Our Platform Engineering team has reviewed and analyzed the log files you provided. Based on this analysis, we can provide the following feedback:
Propagation delay: There is no artificial delay introduced by our platform. Objects become visible across different operations almost immediately, although not strictly in real time.
Object consistency: Once a CompleteMultipartUpload operation returns the HTTP status code 200 OK, subsequent HeadObject requests should succeed immediately. Shortly thereafter, all other operations should also become available.
Based on our log analysis, all multipart uploads were completed successfully. However, we observed subsequent UploadPartCopy requests referring to an UploadId that no longer exists, as the UploadId becomes invalid once an upload has been finalized.
Could you please clarify where these UploadPartCopy requests originate from within your application or client workflow? It appears that after completion of the original upload, an automated post-processing script or background process on your side is being executed, such as a CopyObject operation.
Could you please check now on cloudron side? Thanks a lot!
