That is definitely an error! I rebooted the nodes but it appears that =
their consensus weights in the latest consensus have not been corrected. =
So I just took them down now.

Is not a bug; we were investigating a way to more quickly stabilize to =
an accurate weight. Obviously, we misconfigured that process. Sorry =
about that!

I think at this point I should go back to a stable release and maybe =
generate new keys to avoid this mistake again.

All the best,
Rob
