DNS zone response speed test tool?
I've put monitoring onto my public website, and by far the largest component of the response time it gives me is the DNS lookup -- 4-500ms, which seems entirely unreasonable. Is there a tool that anyone knows about that will measure the response time of my zone servers, somewhere on the web? Is the sum of the times in a dig +trace the proper metric to look at there?

Yes, it is called Nanog. For baylink.com ? Only one real name server and quite slow. % qtest -n 10 "SOA baylink.com" $(dig +short NS baylink.com.) 148 ns5.baylink.com./69.12.222.27 149 ns6.baylink.com./69.12.222.27

Doesn't do much for long term graphing and monitoring, but for quickie issue detection or verification, http://www.grc.com/dns/benchmark.htm ...Todd On Tue, Dec 20, 2011 at 8:00 AM, chip <chip.gwyn@gmail.com> wrote:

Am I mistaken in thinking that's a tool for measuring the efficiency and accessibility of *customer resolver* servers, not zone servers? Cheers, -- jra -- Jay R.

Oops, yeah, I was thinking it would do timing of zone servers, but it's aimed at resolvers. Sorry for the misdirection. ...Todd -- If Americans could eliminate sugary beverages, potatoes, white bread, pasta, white rice and sugary snacks, we would wipe out almost all the problems we have with weight and diabetes and other metabolic diseases. -- Dr. Walter Willett, Harvard School of Public Health
