For what it's worth, I discovered a neat way to host files of almost any size for free online and make them easily accessible: Google Docs.
Google docs will actually let you upload ANY kind of file, host it, and let you share it - not just "office"-like files. Including .zip files and other archive files. I think I may have had to re-name a file suffix at one point for executables (like saving a .exe file as .exe.txt and then the downloader deletes the .txt), but once I realized .zips are okay I put anything problematic in a .zip. And I think .exe might even okay now.
I haven't found any real size limits yet. Just tell gdocs not to try and convert the file. You may get some warnings about blah blah blah but they're irrelevant.
Not that that helps in this case (where a utility site that serves the whole globe has gone down), but it's good workaround for just sharing files personally.
