Re: [tor-relays] Drop in consensus weight

Based on found numbers, some thoughts:

* shouldn't there be more authority servers? DNS system has 13 root servers spread over the globe...

* not all authority servers are equal:

** reported data varies greatly between servers

https://consensus-health.torproject.org/consensus-health-2016-11-08-19-00.html#36EE8D47E570B8D5515460A9972F3CFD9EDFDFCE: maatuska=1400 <> gabelmoo=4060

** some authorities vary greatly in reported data:

https://consensus-health.torproject.org/consensus-health-2016-11-08-19-00.html#36EE8D47E570B8D5515460A9972F3CFD9EDFDFCE: gabelmoo=4060

* authority participating in consensus change, and with only few active (4-5) at a time, impact of a single authority on network is amplified

By having more servers

* consensus would be more stable (low-median)

* leading to more accurate assessment of nodes

* and wider utilisation of the available nodes

* leading to higher network throughput

Does that sound plausible?

Thanks for the link to consensus-health, based data available:

05/11 17:00
longclaw=4540
gabelmoo=4170
moria1=4410
faravahar=2520
=> cons: 4170

05/11 18:00
longclaw=4550
gabelmoo=2170
moria1=4410
faravahar=2520
=> cons: 2520

So that explains the drop.

As far as I can tell, the relay is accurately measured.

Sometimes, this means that you get a lower measurement than you might have
had before.

Accurate bandwidth measurements are a good thing for tor users, even if the
changes in the measurement are sometimes (temporarily) disappointing to relay
operators.

If you want to improve the measurements, try adding more bandwidth.
For your relay, this means increasing BandwidthRate and BandwidthBurst.
