I consider it local, If anything breaks between the filters and the DNS,
it would most likely break all incoming traffic and I wouldn't care.

You're right, the jam was probably the queue for the ethernet card. A
caching DNS server on each machine would have reduced the problem and
probably been much harder to see than the catastrophic failure I had.
If something is going to fail, I like them to fail in the most spectacular
way possible, so it is clearly failed. Intermittent failures annoy me.
