Cannot resolve host for apex domain using netlify DNS

My site at snazzy-entremet-4502bd.netlify.app is working correctly:

$ curl -L snazzy-entremet-4502bd.netlify.app
Coming soon...

And the www subdomain for my externally registered custom domain is also working fine:

$ curl -L www.reviveelectrical.co.uk
Coming soon...

But for some reason the apex domain is not:

$ curl -L reviveelectrical.co.uk
curl: (6) Could not resolve host: reviveelectrical.co.uk

Please could you help in troubleshooting this?

update: the problem seems to be particular to my ISP’s DNS server which is at 212.23.3.100 . If I use 1.1.1.1 instead it works fine.

Hello @barnettjoe - Welcome to our community!

I have tested this from a few different regions and have been able to also receive a proper resolve.

% curl -L reviveelectrical.co.uk
Coming soon...

Were you testing your apex domain shortly after a DNS update? I am curious if this a matter of waiting for DNS propagation to occur for your ISP’s DNS server.

Thanks for being here!
