================= Fail ===============

I have checked the domain edewania.com in dnsreport.com and the report
was ok,
when I logged on to the DNS server and "rndc flush" it, then it started
resolving from both IP addresses

That happens with quite some zones as well, few of them have problems
with their DNS servers and few don't

Thank you.
