Epic did the right thing, after almost 20 years of running the Unreal Tournament 2004 master server, they announced that they were shutting it down, within days a new fan run master server was setup and working, migrating to the new was a simple thing, just edit the main config file and it worked.
Plenty of patched copies of the game can be found on archive.org
