Sorry for the delayed reply…
I had given links to WebPageTest.org, Ultratools.com (https://www.ultratools.com/tools/dnsHostingSpeedResult) but what I think really proved my point was querying directly their DNSes using dig (it’s a Bind DNS tool).
something like
dig @name_of_their_server my_domain_name A
calling this over and over would give the results I gave above, some very good, some very bad and sometimes no answer…
By the way, I finally received an answer from them and I am not impressed…
<<I have received a reply from our systems administrator who agreed that these query times are a bit high, but also stated that a response was still given and this would normally be the last server that is queried after ns1-ns3. If no records were retrieved at all, that would be cause for concern.
I do apologize if this has caused any inconvenience, but although our nameservers historically have very good uptime, if 100% uptime is a necessity you may want to consider a paid DNS management service.>>
First, 2-3 of their servers have performance problems, not just ns4…
Second, anybody who knows anything about DNSes knows the order in which records are returned (including NS (name servers/DNS) records) is implementation dependant but is usually randomized…
The answers I got from their servers clearly show their servers randomize the values, they don’t return them in alphabetical order as their system admin said..
So, what did I do?
Another registrar hosts domain they are not even the registrar for free so I switched to them for my DNSes. The idea behind this, and they clearly mention it, is that if your like their DNS hosting when comes to time to renew your domain you might switch to them…
Their DNS servers are not as fast as the registrar of this domain but they are never anywhere near that slow so it’s good enough for me…
Have a nice day!
