Comment (by cohosh):
I'm also finding that the IP addresses of snowflakes that fail *always
fail*, once I go through the output of the attached stun.lua and do some
manual inspection to remove false negatives. These false negatives happen
because of traffic from old snowflake connections seeping into future
packet captures.
We have a lot of unique snowflakes, but we're starting to see repeats of
snowflakes by IP after 400 runs, and I have yet to come across a case
where a snowflake fails in one use but passes in another. I have seen some
snowflakes that have failed twice on different days.
This is encouraging in the sense that if we can come up with a test to
check reachability, we can eliminate the problem (perhaps with #32938).
