First, I am unaware how this dance takes place. It seems to be the case
that 'Faravahar' has a different understanding of who is a authority and
who is not, but why would it not sign the consensus from 'maatuska'?

Second, since there will be a number of authorities that is divisible by
two it seems that there could be situations where ties would occur
during the voting process. IIRC you've always preferred to avoid that,
so either 'urras' gets replaced or another authority gets nocked down.
(E.g. less people that have to be trusted.) What's your plan? Is there a
ticket where this is tracked?


Poor 'urras' seemed to have and seems to have trouble:
>>> NOTICE: Downloading the consensus from urras took 121.2s (...)

This is likely one of the reasons why you are migrating away from it.


I saw
>>> WARNING: The consensuses published by the following directory
authorities are more than one hour old and therefore not fresh anymore:
dizum

an awful lot, so it could be a candidate for an authority to get rid of,
if 'urras' is not replaced.
