When you go to:

http://dfbredirect.dfbgaming.com:9080/UT99/

or

http://omfgredir.dfbgaming.com:9080/

Do you get a listing and can you download the files?  We changed the dfbgaming.com domain a few days ago and it may have not updated everywhere (although it should have?).  The UT3 sniper redirect is a different story but as far as I can tell from the config and looking at the pages the UT99 redirect should be fine.
