<div style="direction: ltr;">We run our own dns servers mostly because some sites look at where the dns query is coming from and depending on that return results that are local. </div>
<div><br>
</div>
<div style="direction: ltr;">E.g. Facebook. If you resolve using google’s dns the Facebook traffic goes via international however if you resolve off our dns servers it goes via peering in nsw and is a lot faster. </div>

<div dir="auto">I saw the blog post and already had some awareness that this was coming, but there is one question I have for Australian operators.
<div><br>
</div>
<div>How many operators promote services like 1.1.1.1 and 8.8.8.8 to their customers instead of operating their own recursive DNS infrastructure?</div>
<div><br>
</div>
<div>And if you do, what was the driver and then risk mitigation position taken?<br>

a good question. Historically we've advocated against it primarily because we can't fix DNS performance issues related to infrastructure we don't control/own. If your any cast resolver sends you to a CDN point in Hong Kong instead of one in Sydney with 100ms
extra latency… the provider is powerless to stop it.</span></div>

one seems really fast, and quite reasonable in terms of results. I guess CloudFlare have been pretty good at that for quite some time. Will be interesting to see what happens with this though.</span></div>
