[tor-relays] Consensus weight dropped

[Bram de Boer]

All,

Consensus weight of my relays and those of others is still near zero, and
not improving. For a network that attempts to break censorship, it is
peculiar that this is getting so little attention.

Apparently a few malfunctioning bwauth systems is enough to censor
specific Tor relays. Endless research and development effort is put in
tweaking and optimizing the relay-to-relay communication, but having only
a few systems in the world that determine the consensus weight of the
entire network does not seem to trouble anyone. Wierd.

I hope the bwauth operators can find a way to correct the problem. I am
feeling silly spending good money on a high-end server with unmetered
bandwidth that has now been relaying a whopping 300 Kb/s on average during
the last five weeks.

Thanks,
Bram
