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?

130ms is perceivable but still quite small, and you’d only hit it once per domain (per TTL). If you care enough to intentionally use it then I wouldn’t worry about it. You’ll rarely notice the difference.

There are a few other services with similar ethos that you may want to check out as alternatives. Quad9 is the one I remember off the top of my head.

I'm getting 153 ms. I'm in Europe. Other DNS servers are like 40ms.

I was using Quad9 for quite some time, but I had consistent problems with the DNS sometimes not working.

In my local network I switched to pihole with unbound as the resolver. Though this does require a bit more setup. I have unbound setup to serve expired records from the cache & prefetch comment queries, this helps with most of the delay.

On my phone I use dnsforge.de when I am not at home for example, and haven't had any problems with unresponsive DNS so far.
