Currently all downloads are temporarily down according to the latest update on the main page. Just check back every now and then, Jacob didn't specify how long it will take, but I'd be willing to bet it'll be fixed soon enough.
Normally there isn't any limit from zenix, which is what fakku uses most of the time. If you're looking at the user uplaod section, some people use megaupload, which does have pretty strict daily limits.
