Comment (by arma):
Another improvement from removing the weights is, counterintuitively,
better load balancing. We pick our weights right now based on consensus
numbers, right? And those are a) wildly wrong because bwauth is wildly
wrong, and b) wildly variable over time, yet we pick one snapshot and
pretend the network will be close enough to like that for months into the
future. I could totally imagine a situation where a fast fallbackdir gets
5% of the weight, and then it goes slow some weeks later. That's easier to
imagine than the bwauth pulls a bunch of numbers out of a hat and they
turn out to be good numbers some weeks later. Let's not paint ourselves
into that corner.
All of this said, maybe the compromise for 0.2.8 is to leave all the
machinery in place, but ship it with much simpler weights for the
fallbackdirs?
I think Sebastian and s7r make a good point that we should pick relays
that are capable of serving the consensus to clients, and so long as all
of the relays are above some minimum bar, things should work well enough.
