Firefox DoH does not resolve some domains from Ashburn Cloudflare resolvers - connection timed out

www.impetus.com is not resolving with Firefox Cloudflare DoH
162.158.76.61 Ashburn resolver seems to be the culprit.

$ nslookup www.impetus.com 162.158.76.61

;; connection timed out; no servers could be reached

ISP resolves it fine.

Not sure that’s the ashburn resolver IP but it might be a geo-based outage as you suggest. It does resolve in Atlanta, Georgia.

Although this is a messy dnsviz, the domain’s own nameservers aren’t responding apparently https://dnsviz.net/d/www.impetus.com/dnssec/

same issue with urlquery.net from Ashburn resolver 162.158.76.90

(the site does resolve even though http times out)

Same issue with Newark resolver :

$ nslookup p.feedblitz.com 108.162.218.21

;; connection timed out; no servers could be reached

can you fix this ?

Thanks,
