[tor-talk] Invalid consensus today

[Sebastian Hahn]

Hi there,

different threads on this list have already begun popping up about
today's 0700 UTC consensus. The reason is that the dirauths did
not produce a consensus that was signed by all 9, but rather the
vote was split (this happens sometimes and usually causes no great
concern). The dirauth dannenberg was on the winning side of split,
so the produced consensus had just 5 signatures, the minimum
required amount for a consensus to be valid. Unfortunately, its key
changed recently and that change has not yet been communicated via
a new Tor stable release. Thus, any Tor not configured to trust
dannenberg's new key would've rejected the consensus as signed by
just 4 directory authorities.

Now that all 9 are in agreement again this problem is gone and there
should be no more logs appearing from this incident.

Cheers
Sebastian
