$ dig @a.gtld-servers.com masamune.playstos.com +short

The servers for the ".com" domain have glue for this server.

The "quick fix" is probably to use an A record for the www,
instead of a CNAME.

Someone must have registered this as a DNS server for a domain,
or maybe a registrar fouled up updating your records. Have you
updated the registrar details of any domains recently? Check if
other domains have this as a name server.
