Comment (by arthuredelstein):
Here's a table of the same data as comment:27. The second column,
timeout_rate_21394, shows the fraction of connections for each exit that
timed out (after 10 seconds). I also included onionoo relay metadata so we
can look for any patterns:

One thing I noticed is that bad relays have higher than average consensus
weights. Here are the average consensus weights for relays with different
DNS behaviors:
* Bad (always timed out): 38612
* Flaky (sometimes timed out): 10440
* Good (never timed out): 7042
That trend explains why I see higher timeout frequency with Tor Browser
than with my DNS timeout survey script.
