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, -- Eduardo Duarte Gestão e Desenvolvimento de Projetos l Project Development Management *DNS.PT* Rua Latino Coelho, n.º 13, 5.º piso | 1050-132 Lisboa | Portugal Tel: (+351) 211 308 200 Fax: (+351) 211 312 720 dns.pt <http://www.dns.pt> | dnssec.pt <http://www.dnssec.pt> | 3em1.pt <https://www.3em1.pt> | facebook.com/dns.pt <https://www.facebook.com/dns.pt> | pt.linkedin.com/in/dnspt <http://pt.linkedin.com/in/dnspt> Aviso de Confidencialidade/Disclaimer: Este e-mail foi escrito de acordo com o novo acordo ortográfico.
