Hi Daniel -
   You may want to check out Steve Gibbard’s very handy wrapper 
around the RIPE Atlas toolkit which allows for traceroute and DNS 
lookups from thousands of points around the world:

Is there any chance at all I can get you to do a traceroute to

And if you have access to a bgp speaking peer, show ip bgp

whatever the equivalent commands are for your NOS).

131.111.0.0/16 or 2a05:b400::/32. DNSviz can see the domain OK but

Here is a RIPE Atlas measurement towards that IP
https://atlas.ripe.net/measurements/23785597/#!tracemon -- 10 out of
50 probes could not traceroute to that IP, but there didn't seem to be
an obvious single point that they all stopped at (BT and Cogent and
Liberty and ASK4 and Comcast) - this is a somewhat larger than
expected failure rate.
Out of 100 probes
(https://atlas.ripe.net/measurements/23785647/#!probes) , 27 were not
able ping that IP (and 3 haven't reported).

I don't see any interesting BGP events until ~020-01-05 07:00

I don't think the execution is relevant when it was obviously a bad

This is like putting rabid weasels in your pants, and later expressing
regret at having chosen those particular rabid weasels and that pair

No access to BGP at home (on comcast) but traceroutes you requested,
plus traceroute to the google DNS cluster I hit. I'm still getting
SERVFAIL with google but answers with BIND on my home machine, 1.1.1.1,
9.9.9.9 and 75.75.75.75 (A 185.203.204.80).

Thank you for this.

Is there any chance at all I can get you to do a traceroute to
185.203.205.10 and 2a0c:d2c4::53:5:7335

And if you have access to a bgp speaking peer, show ip bgp
185.203.204.0/22 and show bgp ipv6 unicast 2a0c:d2c4::/32  (or
whatever the equivalent commands are for your NOS).

[Google Public DNS engineer here]

As others have mentioned this appears to be a connectivity or load
problem. We are getting successful resolution in about 50% of metros
globally and timeouts in the rest of the metros. The locations are
consistent across 3 attempts.

FWIW we see failures in Belgium but not in Amsterdam.

For Google Public DNS specific problems, you can reach us via mailing
list or issue tracker:
https://developers.google.com/speed/public-dns/groups.

Maybe connectivity problems? I can't get to any of the nameservers from
131.111.0.0/16 or 2a05:b400::/32. DNSviz can see the domain OK but
zonemaster cannot.

Hi,

Any chance that you could provide the output of dig commands showing what
the "bad" responses look like from Google recursive resolvers, and what the
"good" responses look like from other resolvers, so we can examine the
difference?


Thanks,

Hazel

Is there anyone from google on this list?

Every well-known recursor is returning valid results for as57335.net
except for 8.8.8.8 and 8.8.4.4 and I'd like some assistance getting
down to the root of the issue.
