DNS outage issues?
Hi,
Is anyone having issues with DNS servers not finding your CloudFlare sites, resulting in users seeing "Safari cannot find this server" errors today?
Particularly with Australian DNS servers:
Only 1 out of 8 common Australian DNS servers are finding our site today. Pic attached.

If that screenshot is from https://www.gdnspc.com/dns-propagation-checker/au.html, I would ignore it...
It doesn't really seem to matter what you're querying for on there, it will be different as night and day...

Re-try by hitting the Search button once more, and you're eventually (un)lucky, and end up with seeing a ✅ or a ❌ more (or less) than before.Yeah, thats the checker I used and I agree it seems dodgy. However this comes from a user report, who was in Australia - and they asked all their friends to check the site on different devices and ISPs and they were all unable to access the site.
I asked the user to try using 1.1.1.1 and it loaded - so definitely an Australian DNS issue.
Do you have any information from the user about what ISP they are using?
Perhaps the AS number of their ISP, - which can be seen on e.g. https://bgp.tools and/or https://bgp.he.net ?
Didn't get that info, but was told their friends were with different ISPs and all had the issue, so it appears more widespread than one ISP.
Seems unrelated to Cloudflare (?), and out of our control I suppose.
https://dnsmid.com/australia/ seems to work for all their locations (albeit, the third one ("AS2764 AAPT Limited")) seemed almost to be "double as slow" than the others to me.
Yeah, same result here. The issue probably fixed itself by now.
Does the domain / hostname from your screenshot belong to you, so it's an user of your stuff, or are you just trying to help someone get to someone else's website?
Yeah that's our site, and the outage report was from a user.
You might be DNS filtered in Iran, but other than that possibility, I don't see anything related to DNS. 🙂
Great, thanks for checking! Appreciate the help.
