Hi all,

After the recent launch of the Quad9 service I try to discover if it had a best response time them my actual resolver, that is google public DNS.

To do this I launch a comparing measurement using atlas that would run during one day to the same address from the probes in my ISP.
The address that I was trying has a very high TTL so I was expecting to always hit the cache of the servers and them get a good comparison base.
I know that there are other factors involve in server response time but to my home connection I fill that this where enough.

When I got the results from the measurement they were not what I expected.... The measurements to Quad9 had high value of REFUSAL.

Does any one as a clue why???

The measurement result is available at https://atlas.ripe.net/measurements/10269508

Best regards,
