There are some running from Australia as well, so those who have a bad connection or connection issues from overseas of the USA can use that one as an alternative. There used to be a German based server from DC-Arena but they seem to be all but gone...could be wrong.
the dc maps can be found in download section with link to my dropbox. mrneo also mirrored the files in the dropbox for me seeing i only have a free dropbox.
not sure bout stream version working as haven't tried it tho if ya using windows just need to install the 1.16n pointer and pop the pak0.pk3(should be apart of the stream install) sega.pk3 dcmaps.pk3 into the baseq3 dir and it'll run. check onlineconsole for a guide with windows, tho the linux guide wont work with modern distros but i managed to get it going and have posted a brief guide.
