Comment(by arma):

 Replying to [ticket:4256 tmpname0901]:
 > I suggest that minimum bandwidth requirements be tied to uptime
 duration.  For example, a node that has been operating for a month must
 have at least 20KB of Observed bandwidth to be considered a valid node.
 This would allow nodes to demonstrate low-bandwidth while ramping up to
 their configured bandwidths, but prevent zombie nodes from falsely
 claiming to be capable of carrying Tor traffic.

 I think it's very likely that such a design would make the network more
 brittle. Either we pick minimum cutoffs that are so lax they have no
 effect on a reasonable network, or we pick parameters that will turn into
 poor choices as the network changes.

 The other question is what the consensus weights are for these 'useless'
 relays. I assume they're tiny, leading the relays to be used very rarely.
 And so long as a relay has some minimum useful bandwidth, we want clients
 to be able to choose it, even if rarely.

 See #1854 for discussion about raising the minimum bandwidth considered
 useful -- somewhere in there we should also decide whether we mean
 consensus bw or descriptor bw.
