Maybe it should be changed to "udp://open.demonii.com:1337" like all the newer torrents? This new tracker is accessible worldwide.
udp://open.demonii.com:1337 is by far the best
also
udp://tracker.openbittorrent.com:80/announce
udp://tracker.publicbt.com:80/announce
http: //open.nyaatorrents.info:6544/announce , which i guess you can use for things other than anime
udp://tracker.ex.ua:80/announce
udp://coppersurfer.tk:6969/announce
udp://9.rarbg.com:2710/announce
udp://glotorrents.com:6969/announce
and istole.it still works i guess
