Hey gang, I’m considering using DNS4EU in Canada. My ping to their servers is ~130ms. That’s way longer than anything local which is on the order of 1-5ms. Apart from resolving uncached entries taking longer, is there any contraindication to using a DNS server with high latency?
Not asking for a workaround. Asking if I’m missing some problem with using a slow DNS server I might run into, other than the obvious one.
The only task of a DNS server is (or should be) to tell you how to get to a resource you’re looking for by name. So, the only thing that is going to be reallistically affected is your (initial) connection times. And – since this is c/selfhosted – if you are setting a decent DNS cache in your local network, that should be even less of an issue.
The only borderline scenario that I could see feasible, since this is c/selfhosted , is that some software you are setting up that requires nanosecond DNS resolution or somesuch sillyness is going to fail or report false errors. But why would you even do that?
And that’s not even letting on that literally ALL DNS queries work from cache unless you are specifically doing a live query.
None of your software is. It’s asking your OS. Your OS is asking your resolver service. Your resolver service is asking your router. Your router is 5000% caching DNS queries.
