I think we've resolved this issue at both ends: Relays should not experience the 0 DirPort issue when upgrading to the next 0.2.7 release. https://trac.torproject.org/projects/tor/ticket/18050 <https://trac.torproject.org/projects/tor/ticket/18050> In the 0.2.8-alpha series, we use a shorter address stability period to work around previous address changes due to the 0 DirPort bug. (This is ok, because fewer people use the alpha series, and they don't use it for very long before upgrading.) https://trac.torproject.org/projects/tor/ticket/18086 <https://trac.torproject.org/projects/tor/ticket/18086> Tim Tim Wilson-Brown (teor) teor2345 at gmail dot com PGP 968F094B teor at blah dot im OTR CAD08081 9755866D 89E2A06F E3558B7F B5A9D14F
