Is this still not working for you? I get 3 answers from my 1.1.1.1 at SJC

If it’s not working, can you type in:
dig +short CHAOS TXT id.server @1.1.1.1
and post the result?

I’ll take a look, the problematic colo from above command would be super helpful.

It started working again after a few hours. Noticed another problem now though. 1.1.1.1 is no longer being served from your Perth DC.

To get to your WAIX router:

Galactium:~ craig$ traceroute 198.32.212.107
traceroute to 198.32.212.107 (198.32.212.107), 64 hops max, 52 byte packets

But to get to 1.1.1.1

Galactium:~ craig$ traceroute 1.1.1.1
traceroute to 1.1.1.1 (1.1.1.1), 64 hops max, 52 byte packets

 8  one.one.one.one (1.1.1.1)  43.203 ms  43.832 ms  46.448 ms

I am pretty sure this used to work and be lightning fast.
