our firewall lost DNS to 45.90.28/30.165 3 times now

Sydney, Australia internet via AARNET

So, today @ 10:50, last Friday 28/10 at 9:30 and 2 weeks before that at the same time - we just lost contact with the DNS servers:

C:\>tracert 45.90.28.165

Tracing route to 45.90.28.165 over a maximum of 30 hops

... to 30 hops.

we had to change firewall & server DNS to bypass nextDNS but left a terminal open pinging until it came back up.

Not helpful couldn't find a reason for this on nextDNS's site.

Anyone else have this issue?

    Hop #5 is showing a non routable IP address.    The router at hop 4 is misconfigured

    Hi, we've re-routed to another provider and it should work now according to the results from AARNet Looking glass

    Please run a diagnostics if the issue persists.
