Every time the root zone data expires the nameserver needs to get a fresh
copy, and if the root servers aren't answering at that particular time,
you'll get the error messages cited above. The nameserver will keep on
retrying, and if it eventually gets through to a root server, then it'll
be happy until the next time the root zone data expires from the cache.

So tell the root-zone administrators to raise their TTLs. Or make yourself
a slave to the root zone.
