http://www.jazz2online.com/downloads/upload/ gave me an error upon submission (don't remember what it was). The upload still appears in the downloads section, but the associated file is not uploaded. Editing uploads, including reuploading the files, works fine, so http://www.jazz2online.com/downloads/7217/battle12/ was missing battle1s2.zip for about one minute (see the upload description for why I don't remember much about the error).
