Thread:Project:Support desk/Uploading a 2GB Zip file Timeouts/reply

Since you have a dedicated server (whoa, awesome!) I suggest you don't upload your zip files here but on subversion. MediaWiki was not designed to host zip files and if you wanted to make a zip uploader I'd tag Template:Extension_by_patch_warning. The latest version of MediaWiki, or any version at all, comes from SourceForge or SVN. Just saying.
