Just got on this thing (perhaps very belatedly) - root server trouble?

What do you think happens to the nameservers on the net when they're asked
for a domain that doesn't have functional servers, and they sit and churn
trying to resolve the names?

They use 30 bytes of memory per such query, during the time it takes to
get back an NXDOMAIN, which is then cached for at least five minutes.

Perhaps you had a point to make?
