Comment (by cypherpunks):

 I've got a question about the semantics of the measured flag for non-
 running relays.

 Total stats from 2015-08-16 04:00:
 {{{
 +----------+---------+
 | measured | #relays |
 +----------+---------+
 |     NULL |     956 |
 |        0 |     338 |
 |        1 |    6659 |
 +----------+---------+
 }}}

 First I thought onionoo does not provide the measured flag for all non-
 running relays, but there are also non-running relays with measured set to
 'True' and 'False'.

 Lets look at an example (non-running relay, no measured flag data in
 details document, but the last known bw entry was actually based on bwauth
 data) from relays_published '2015-08-16 04:00:00':

 }}}

 5 BWAuths provided measurement data.

 Why does that relay have no 'measured' flag in onionoo's details document?

 thanks!
