We're with Digital Ocean (DO), but I suppose this question applies to anyone hosting anywhere. In the Dnsperf rankings, DO is quite high, but in UltraDNS DNS speed tests, my domains hosted with DO come up much slower than others hosted with GoDaddy. The difference is to the tune of 90ms on DO compared to 2ms on GoDaddy.
Question: do these tests tell me anything about DNS speed, or are they always relative to wherever the test server (from UltraDNS in this case) may be? We're trying to speed up our DNS and have tried the likes of DNSMasq on our 'droplet' VPS server, but the DNS speed tests results remain the same.
Are we over-engineering? Would love to hear any guidance on how to make our DNS work at the best possible speed. Thanks.
