@jerry Sorry to bother you.

@jerry Sorry to bother you. Are you aware of any issues with DNS for infosec.exchange. For some reason I am unable to resolve on my unbound recursive resolver.
If I try to resolve it with any other DNS provider Quad9 etc it resolves.

Though if I try to query from the root serves backwards I start to get the same errors:
;; communications error to 199.247.152.53#53: timed out

I may be being dumb and going about investigating this the wrong way with my limited DNS knowledge.

Just wondered if you knew of any issues with the root nameservers fro the exchange TDL.

Sample of dig commands on the various nameserves:
dig infosec.exchange @127.0.0.1 -p 5335
;; communications error to 127.0.0.1#5335: timed out
;; communications error to 127.0.0.1#5335: timed out
;; communications error to 127.0.0.1#5335: timed out

; <<>> DiG 9.20.21-1~deb13u1-Debian <<>> infosec.exchange @127.0.0.1 -p 5335
;; global options: +cmd
;; no servers could be reached

@aircooledcafe I'm not aware of any problems - I host dns with dnsimple and their status page isn't showing any problems (https://dnsimple.statuspage.io/) and all the checks I can run come back without a problem:

dig infosec.exchange @ns1.dnsimple-edge.net
