Just browsing through my routing table status servlet and noticed
something worrying - a backed-off node whose last estimate was -27143ms.
Presumably we shouldn't be getting negative estimates for routing times.
I looked through the node's estimators and couldn't see anything
obviously

Hmmm, just found another 6 of them in my RT - it looks like this

Since QR backoff was implemented, upgraded nodes have probably queried
far less than they did before. However, non-upgraded nodes are still
over-querying. In fact, we might reach a point where we have 10% of
connected nodes using the old version, but see

Many nodes now exceed their output bandwidth regularly and as a
result issue many QRs. We are trying to reduce the bandwidth wasted
sending QRs, and the waste of resources which occurs when a deeply
chained request gets QRed. The node which first receives the QR
does not try again with a

it would if it got a DNF. Instead, it passes the QR back, and

We need to reduce the number of queries coming from nodes which don't
use QR-backoff. A few ways to do this are:
1. Keep track of each node and punish those who don't back off.

don't back off. (The following two ways would

QR meant DON'T back down the chain, just try another path and
that DNF meant send a failure all the way back down the chain,
as the HTL has been exhausted.
In fact, that's
