Since several weeks or months, upload for large files is essentially broken.
It is now nearly impossible to upload a file larger than 100 MB. All file formats are affected (PDF, TIFF, videos, etc.). Upload even failed for a 77 MB TIFF file from Internet Archive.
See https://phabricator.wikimedia.org/T292954 for details.
There has not been much feedback from developers.
However this is a serious issue and needs an urgent fix.

As consequence, a Server side upload was requested:
The task is waiting for 3 weeks without action for a routine task which should take only a very short time. I wonder if there are still developers alive...

Instead of fancy features development, WMF budget should be used on priority for maintaining the existing functionalities. Uploading large files used to work very well, so why has no effort been done to fix this bug?
