We operate an open BitTorrent tracker at:
udp://exodus.desync.com:6969
The tracker originally served to coordinate the distribution of software in our infrastructure, but has since become useful to the Internet at large. It's also good at finding bugs and performance regressions in our network stack. We consider it a public service and do not record any information about usage of the tracker beyond the generalized statistics available on this page.
Be aware: the BitTorrent tracker protocol precludes the ability for us to know what data is represented by a given hash. In other words, we do not know and have no ability to control what is being shared among peers. Abuse of the tracker (such as excessive scraping) will result in revocation of access.
Also, it should be obvious, but if you see the tracker in DNS requests, firewall logs, etc, you are connecting to us, not the other way around. We are not scanning or trying to hack you.
Software used is currently the excellent opentracker program.
Do not email us about the tracker. Enjoy!
