[nSLUG] Eastlink DHCP oddness

While I am not familiar with your problems, I have had a massive issue
with the Eastlink DNS for 2 years or so: Any DNS resolving with my
Ubuntu PC (and some other Linux devices) takes a very long time. Over
one second. I believe there is some timeout that has to be waited for,
but I couldn't track the real issue down.

As the average website-load today requires several resolves, browsing
the web became unbearably slow. Once the domain was resolved, everything
flowed quickly.

I've been in touch with Eastlink support when the issue arose, but to no
avail. Eventually, I switched to other DNS.

Maybe someone can find a connection between your discoveries and my
issues, maybe not.
