What DNS forwarder servers is everyone using out there?

My organisation is currently using some old clear.net DNS server but they frequently have micro outages so am going to change

Apart from the go to public google servers can anyone recommend some reliable, fast & local servers?

Cheers!

I personally would recommend using your ISP dns servers, I like to have a soft fallback to google DNS in the event there is an issue with resolution.

all ran through dnsmasq so transparent for the users.

Cheers, I had been leaning towards that setup ISP(Vector) then to Google's

Funny, as I went to submit this thread it timed out.. DNS was down again..

Yes, the best option is almost always to use your local ISP's DNS servers as you should get best performance from them. I can't remember what it's called but a while back there was a tool that let you enter a whole bunch of DNS servers and it would test the latency to each of them. If you're having DNS performance issues, that would be a good option. You'll probably find that Google's DNS servers have quite high latency due to the physical distance to them.

Google DNS should land you with the Sydney nodes from NZ which isn't too bad, but obviously local would be better.

Absolutely though, local ISP DNS so you hit their akamai nodes etc, just having that backup case in rare downtimes is handy.

It's hardly surmising clear.net DNS servers aren't working correctly if you're not on their network. You'd have to be crazy to be an ISP and allows lookups from outside your network these days.

Using your ISP's DNS servers is *always* the best option. That ensures CDN's will work correctly. Failing that Google is great as an emergency failover.

Sounds like your talking about this DNS benchmark

Why would you not use the DNA servers of your ISP? This makes no sense

Time outs don't mean 100% an ISP issue either

Please tell us your logic in using another ISPs DNS server's?

It was a DNS issues and they were set to that before I started. It's hardly something I've done in that past to go actively checking the DNS forwarders of networks I've inherited unless there are suspected DNS issues.

I'm no DNS expert and just assumed because there are many publicly available DNS servers that some were better to use than others.

I'm glad I came here to ask for advice first as I was given some good and after reading, yeah it makes perfect sense to use your ISP's DNS servers.

Changed now and have had no problems again since.

Again, thanks to all that helped.

Cheers,
