The only thing I can say is that this domain is served by four name
servers but they seem (from their IP addresses) close to each
other. Which means a single routing issue may make the domain
unresolvable.

Try with dig to see if it's the case:

dig @dns1.registrar-servers.com A anidb.net

dig +norec @dns1.registrar-servers.com A anidb.net
