isoHunt: improving BitTorrent scalability and reliability by cross-referencing trackers

Why do I link to torrents on isoHunt whenever possible? Because isoHunt is the only torrent site with this cool but seldom talked about feature: tracker cross-referencing. The feature was implemented back in 2005 and is still invaluable.

Identical torrents across the web are often tracked by different trackers. Users might submit identical torrents to different sites using different trackers. Some tracker sites inject their own tracker into torrents. isoHunt caches one copy of these identical torrents (with the same hash), and edits the torrent to include every available tracker tracking the torrent. Therefore, when you download a torrent from isoHunt, you get maximum reliability and performance due to the redundant trackers that can pick up the slack even when the primary or original tracker is down or slow.

Remember to use redundant trackers when you create your own torrents too.

And for those who aren’t aware, isoHunt is an awesome meta search engine. It indexes practically every public torrent site on the web, and there’s generally no benefit to using other meta search engines instead of isoHunt. Check out the list of sites indexed by isoHunt. Be sure to shoot Gary an email if you know of sites that are not indexed.

20+ open and public BitTorrent trackers

Here is a list of BitTorrent trackers I know of that track any torrents, whether you upload the torrent to their site or not, and track for any users whether they are registered on their sites or not. Basically, if you need trackers for a torrent that’s open to the public, use these trackers. In fact, use all of them so that you have super-duper redundancy in case your primary tracker goes down. One of the weaknesses of the BitTorrent protocol is its reliance on centralized trackers. The use of redundant trackers (along with the DHT feature) all but eliminates this weakness. Read on for the list.
