DNS fanout for NTS

ntp.glypnod.com now returns the IP addresses for ntp1.glypnod.com and ntp2.glypnod.com The certificates on ntp1 and ntp2 have SAN (Subject Alternative Name) setup so the certificates on ntp1 and ntp2 are also valid for ntp. That means that server ntp.glypnod.com nts should work. It does
