What If The TRACKERS Down/Dead?
Unfortunatly if the TRACKER goes down, which then often can do, then you will need to wait to see if it comes back on-line again.
There really is nothing more you can do.
To see what state a TRACKER is in, you can use a tool called TORRENTSPY which can tell you alot of information about the tracker.

If the Tracker is 'DEAD'. Then sometimes, the person(s) who make the torrent, use whats called a Back-Up Tracker, which is exactly as it sounds, if the original Tracker dies, this one will fall in to replace it.
