[dns-operations] gov.mu inconsistency

[S Moonesamy]

Hello,

I have been trying to debug an issue affection domains in the gov.mu 
zone.  On 4 November, I would only get an A RR for www1.gov.mu if the 
DNS query when through udns2.tld.mu and fork.sth.dnsnode.net:

   mu.                     172800  IN      NS      fork.sth.dnsnode.net.
   mu.                     172800  IN      NS      udns1.tld.mu.
   mu.                     172800  IN      NS      udns2.tld.mu.
   mu.                     172800  IN      NS      anycast1.irondns.net.

   dig soa mu @fork.sth.dnsnode.net +short
   udns1.tld.mu. hostmaster.nic.mu. 2014110644 21600 3600 604800 86400

   dig soa mu @udns1.tld.mu +short
   udns1.tld.mu. hostmaster.nic.mu. 2014110644 21600 3600 604800 86400

   dig soa mu @udns2.tld.mu +short
   udns1.tld.mu. hostmaster.nic.mu. 2014110644 21600 3600 604800 86400

   dig soa mu @anycast1.irondns.net +short
   udns1.tld.mu. hostmaster.nic.mu. 2014110644 21600 3600 604800 86400

The serials in the above are the same.

 From anycast1.irondns.net (195.253.64.5):

   gov.mu.                 43200   IN      SOA     ns1.gov.mu. 
gov.mu. 2014110644 10800 3600 43200 300

 From udns1.tld.mu (204.61.216.10):

   gov.mu.                 43200   IN      SOA     ns1.gov.mu. 
gov.mu. 2014110644 10800 3600 43200 300

 From ns0.gov.mu (208.94.148.2):

   gov.mu.                 43200   IN      SOA     ns1.gov.mu. 
hostmaster.mail.gov.mu. 2014010572 43200 3600 86400 180

 From ns1.gov.mu (208.80.124.2):

   gov.mu.                 43200   IN      SOA     ns1.gov.mu. 
hostmaster.mail.gov.mu. 2014010572 43200 3600 86400 180

 From ns2.gov.mu (208.80.126.2):

   gov.mu.                 43200   IN      SOA     ns1.gov.mu. 
hostmaster.mail.gov.mu. 2014010572 43200 3600 86400 180

 From ns3.gov.mu (208.80.125.2):

   gov.mu.                 43200   IN      SOA     ns1.gov.mu. 
hostmaster.mail.gov.mu. 2014010572 43200 3600 86400 180

The serials for gov.mu are not the same in the above.  Is there a 
problem with authoritative name servers for .mu or the gov.mu?
