really need dns assitance

[cosmicfantasia]

Hi Swsoft Community,

I am a small Australian based hosting company and have 2 plesk servers in the US to run my hosting and dns on.

I have Bind on both machines and have a Master/Slave setup that works fine.

I am having intermittent issues with domains with .au TLDS resolving. It is very intermittent. Sometimes working, sometimes not. Other domains such as 1770southerncross.com (which is on the same server) don't have any problems. Just the .au domains.

One of the domains that I am having issues with is http://cosmicfantasia.net.au

When doing a DNS report on this domain I get different results as well. See:

http://www.dnsreport.com/tools/dnsre...antasia.net.au

Sometimes i just get the glue warning, then sometimes it gives me FAIL's for DNS servers have A records and no NS records. Has anybody got any ideas what is happening and why only on and off? The dns record for this domain is as:

$TTL 86400
