On my DNS server when I make nslookup for some site I have this message ** server can't find XXXX: SERVFAIL but the site found and resolved on other servers, what I have to check
I've had this for quite some time as well. It seems to happen with sites which has a lot of information in the DNS record (like many IP addresses). Sometimes the same sites work, probably if the record is slightly rearranged (reordered IP addresses or so).
It is a problem with bind but I haven't been able to look deeper into it.
