[tor-relays] sustained bandwidth drop through noisetor

[Mike Perry]

Thus spake Andy Isaacson (adi at hexapodia.org):

> noisetor-01 was pushing 300-400 Mbps of traffic from 2012-02-15
> through 2012-04-13.  Since mid-April we've seen traffic decrease
> significantly; over the last week, our daily peak has been 260 Mbps
> (versus 450 Mbps in March) and our daily trough has been 100 Mbps
> (versus 300 Mbps in March).
> 
> The traffic levels dropped off in a smooth fashion over a 10 day period,
> April 15-25 if I read the graphs correctly.
> 
> Has there been a change in the routing algorithm, or any other network
> changes that might explain this drop?

The loss of non-TBB Torbutton users might explain a drop post Apr 20th,
when their ability to move tabs around was borked by FF12:

But otherwise, according to
https://metrics.torproject.org/consensus-health.html, all 5 bw auths are
voting, and I have not changed the algorithms.
