Authorities don't serve version 2 statuses anymore. + + Since January 2013, there was only a single version 3 directory + authority left that served version 2 statuses: dizum. moria1 and tor26 + have been rejecting version 2 requests for a long time, and it was + mostly an oversight that dizum still served them.
