For me it works for some reason. Many topics were created about the same issue, but it seems like some locations are affected by that issue. Can you please do a traceroute of ns1.epizy.com? That should also show the location you’re trying to connect to to resolve your DNS.

Your message, and those from others, have clearly helped to indicate that the Los Angeles DNS servers were malfunctioning. This has been corrected now. Can you please check if your domain works now?
I checked the DNS for your domain from our own monitoring node in Los Angeles, which returned the correct DNS records.
Do you still get the DNS domain not found error? If so, this may just be caching at your DNS resolver, rather than an issue with our nameservers. You could try to clear your computer’s DNS cache or try another DNS resolver like Google Public DNS or Cloudflare’s 1.1.1.1 service.
