Hi Casey,

There are clearly two versions of the zone being served by gov.mu
servers. If the value of the serials is any indicator of date (as
it appears), then udns1.tld.mu and anycast1.irondns.net are serving
a version of the zone that is about ten months newer than that being
served by ns{1,2,3}.gov.mu (2014110646 vs. 2014010572).
The strange part (re. date) is that I got a serial of 2014010166 on 7
October from a resolver.
Note that udns1.tld.mu and anycast1.irondns.net are *not* in the NS
RRset for gov.mu (i.e., aren't explicitly designated as
authoritative), but they *are* authoritative for mu, and do also
(stealthily) answer authoritatively for gov.mu, which means that
your resolver will accept their answer when it queries mu for
something in gov.mu (although it will learn the designated NS names
in the authority section of the response).
Thanks for the explanation.
Regards,
S. Moonesamy
