Maybe your are using the providers nameserver, beside a lot others, so 
the providers nameserver itself may be blacklistet because of too much 
reqeuests, and therfore gets no(or only sometimes) answers from the dns 
blackalist severs. This also happens if you are using google's dns

If this is the problem, providing your own Nameserver may be the solution.
