The tracker has been down at last 24 hours, but it could have been weeks for all I know. This orphans any torrents created as private and hence no DHT, for example:

[CORRECTED] Queen & Status Quo - 1985-07-13 - Live Aid, Wembley Stadium, London, England

Hmm, if I just double click the link in the posting above on my laptop I get a text file which says:

I've restarted uTorrent so that's not the problem.

Here we are 3 weeks later and the Queenzone tracker is still not working.

And still not working. Is anyone even looking at fixing the QueenZone tracker? Some of the torrents are orphaned as a result, where people naively created them as private torrents ie. DHT not allowed.
