 This morning, we had this fun notice from doctor:

 {{{
 ERROR: Unable to retrieve the consensus from moria1
 (http://128.31.0.39:9131/tor/status-vote/current/consensus.z): Error -3
 while decompressing data: incorrect header check
 ERROR: Unable to retrieve the vote from moria1
 (http://128.31.0.39:9131/tor/status-vote/current/authority.z): Error -3
 while decompressing data: incorrect header check
 }}}

 The file from that hour is available at
 http://seul.org/~arma/consensus-20170508.z.

 The next weird thing is that using three different wget versions from
 different platforms, using

 {{{
 wget http://128.31.0.39:9131/tor/status-vote/current/consensus.z
 }}}

 to fetch a consensus from moria gives an uncompressed file. yawning and I
 can reproduce that, arma can not. Something fishy seems to be going on?
