After more than a few people asking we are now adding access to the network via TOR. Currently we will still maintain the ban we have on accessing us on our public interfaces from tor or an open proxy.
Our hidden service address is ircnetdbe6ohrrrekzbf33v7crjink7hsafrtzyid6rof4jianus4byd.onion on which we will only listen on with ssl on port 6697. More information about tor can be found on the TOR Project website and we highly recommend the TOR Browser Bundle.
Update 2018-11-13: Updated hidden service address
Update 2020-10-01: Tor V3 address
