And let's see, what is the difference in their setup? Could it be that
they are using DHCP and thus receive new network configuration changes,
such as, uh, DNS and GW, every time they boot up. Ain't technology
amazin'.

Linux isn't broke but it also didn't change. Your ISP's networking IPs
changed and you won't be automagically updated using static info.
Sorta the purpose of using DHCP.

Exactly the problem.

Because it is having to route packets through a convoluted -- probably
low priority -- DNS pathway.

Well, duh, yeh they changed something. Their DNS servers. Your
Windows machines are fully informed of this but you have failed to
inform your Linux boxes of the changes. Don't blame your ISP if you
choose not to use their resources or keep your set up current.

Just the person controlling the machine. If you use static networking
settings on a network set up to use DHCP, don't be surprised when
changes are not automatically reflected in your static setup.

If you set up your Linux boxes to use DHCP, they too will enjoy the
wonders of DHCP and will be automatically informed of network changes.
DNS servers, especially, are prone to change IPs as a result of
maintenance, failures, re-configuration, etc.

It's your choice ;-)
