OK delete this if the info is already here - someplace - but it would help if it could be stated prominently on or near the front page because despite looking briefly I can't find it.
What is/are the current tracker/s for concen.org?
Inspecting the innards of a couple of recently upped I see
udp://concen.org:6969
but no
http://concen.org:6969/announce
- has the https version gone or is it temporarily 'resting'?
Neither. ConCen has never had an https announce.
