Yep. It had me stumped for a while a couple of months back when a bug in
dhcp (IIRC) caused the route table to get chewed to bits. I could
resolve an IP, but not a name.

The problem comes knowing which part has been chewed. Remember, those
testing may specialise in one area and know not very much about another.
I know quite a bit about the compilers and desktop apps, but not a huge
amount about the networking side of things.
