Does tracker.ccc.de work for anyone anywhere in the world besides .at, .ch & .de?
Maybe it should be changed to "udp://open.demonii.com:1337" like all the newer torrents? This new tracker is accessible worldwide.
Edit: After reviewing the recent statistics of reach-ability of demonii.com I no longer recommend it.
What about other trackers? Open, less politicized, trackers, that aren't associated with thepiratebay.se? Or maybe differently politicized trackers associated with other organizations? While those 4 trackers are reliable and well defended against DDoS, they are also the ones that are most commonly blocked/censored/filtered by various software nannies.
