strange problem..

I've got a strange problem with all my domains on my server.

Sometimes, well it happens quite often, I get a DNS Lookup Error for all my domains on the server, and a few hours later it is back to normal without me doing anything..
Strangely enough, my nameservers are always available
The nameservers and the A record for each domain seem ok though..

Two domains that have the problem:
http://www.dromedaris.be
http://www.volcano.be

Anyone knows what the problem could be and what I can do to solve it?
