What is --- WRONG --- with my network?

Fri May 6 05:37:25 PDT 2005

Hello boys!

I just spent a few days doing a make world and kernel.
My machine is terribly slow. Yet, my network problem hasn't
gone away. This shows that it wasn't an asynchronisation
between my world and kernel. I've also compiled io and mem
into my new kernel.

Here is my problem description:

*  My nameserver setup is disfunctional.
*  My web, mail and fileserver is disfunctional.
*  I cannot SSH and FTP into certain servers.
*  I cannot ping my IP from the outside.
*  My ISP controls the PTR of my reverse DNS lookup.
   This fails to resolve too.

PF is disabled.

My configuration has been running flawlessly for the past
few months before this strange happening occured. I know for
a fact that this is not related to a misconfigured rc.conf
or named.conf. Maybe it is my ISP?

Somebody please assist me.
This is a medical emergency!
