Yes, that and some other issues, I just wasn't sure if you meant during
friday night saturday morning or more recently.

the caching.<<

Lighten up, I was just asking if you had tested to see if it was the cache.
I still hope to someday reproduce the problem for you.

>>   It may interest you that the most significant DNS problem I have is
with IPv6.  There are DNS servers which mishandle requests for IPv6
addresses and fail with internal errors or much worse incorrectly report
that the name queried for does not exist.  The name doesn't exist error is
cached by other DNS servers.  If you want an example, install IPv6 and try
to access www.cdw.com.<<

I still haven't purchased the equipment I need to setup here at home to
play with v6 properly so no experience on my part yet. Interesting issue
though, any idea which dns servers have this problem?
