[tor-relays] Relay MIGHTYWANG consensus issues and loss of STABLE flag

[Mighty Wang]

Hi Eddie

Yes I saw your post on the day it happened and guessed that we are 
suffering from exactly the same issue that started at exactly the same 
time.

I couldn't correlate the loss of stable flag with anything in recent Tor 
server releases but I am going to recheck those; I am currently working 
my way back through the consensus voting lists in the run-up to the 14th 
October to try and understand where the problem started,

I'll report back here.

thanks


W
