Uploads are not working on pre.gitlab.com

On upload we see the following:

{"correlation_id":"IeWPvzQdIh4","error":"handleFileUploads: extract files from multipart: persisting multipart file: uploadLocalFile: mkdir \"/mnt/storage/uploads/uploads/tmp/uploads\": mkdir /mnt/storage/uploads: permission denied","level":"error","method":"POST","msg":"error","time":"2019-07-02T06:38:40Z","uri":"/jarv/registry-test/uploads"}
