mydomain.com primary name server = ns1.vodafone.co.nz responsible mail addr = hostmaster.mydomain.com serial = 2018030703 refresh = 28800 (8 hours) retry = 7200 (2 hours) expire = 604800 (7 days) default TTL = 7200 (2 hours)
It looks like some of Google's load-balanced name servers have the old, correct data and others have refreshed from Vodafone with bad, non-existant data.
Has anyone else come across this before or know how to fix it.
I have duplicated the DNS records to a different DNS provider but am waiting for Vodafone to respond to my request for them to change the authoritative name servers for our domain to the different provider.
I'm now finding that our A, TXT and CNAME records are failing in the same way.
