Ask HN: My website just disappeared from DNS. What can I do?

My website -- http://xordle.xyz -- has just disappeared from DNS. It's been working fine for months.

My registrar is Google Domains; there's no errors reported in the DNS settings or anywhere else. But Google's own DNS query at https://dns.google/query?name=xordle.xyz returns a status code 3 -- NXDOMAIN, or no such domain.

I tried transferring to a different registrar but it can't be transferred on account of it "not existing". I tried using Google Support; they weren't helpful in the slightest.

Do I have any options aside from just getting a new domain name if it doesn't resolve itself quickly?
