 It looks like the new Onionoo host orestis has too slow I/O for the
 background update process.  That process is supposed to run once per hour
 but takes up to 1.5 hours on orestis:

 {{{

 }}}

 The same background update process runs for about 25 minutes on omeiense:

 {{{

 2017-02-11 15:15:11,391 DEBUG o.t.o.cron.Main:147 Started update ...
 }}}

 If you can, please confirm that I/O is really the issue here.  And if so,
 can you move orestis to a host with faster I/O similar to that of
 omeiense?  Thanks!
