[clug] DNS weirdness

This isn't really a linux question but it is a network question so 
hopefully on topic enough to keep people happy.

My ISP is Netspeed.  A couple of particular websites I want to view, 
www.intelligentflight.com.au and forum.intelligentflight.com, seem to be 
doing weird things in Netspeeds DNS. Right now, if I dig either of these 
names on Netspeeds primary DNS (dig @ 
www.intelligentflight.com.au) I get status SERVFAIL. If I dig against 
their secondary DNS (dig @ www.intelligentflight.com.au) I 
get status NOERR and the name is resolved. At other times of day the 
primary DNS works though, but most nights at 8 or 9 it doesn't. Its 
making it a bit tedious to actually access the websites. No other web 
sites I use seem to suffer like this.  Is it possible to tell if this 
likely to be an issue with Netspeed DNS, or with the web sites hosting 
service, or something else?
