QWest is having some pretty nice DNS issues right now

I didn't get to play detective at the time of the outage, but
configutation (which is automatically replicated) may also have been
enough to take out both nameservers.

It also makes good management sense to run your nameservers with the
same software and versions, but perhaps it doesn't make good continuity
sense.. ?

That may not be necessarily true. Vendor diversity is not a bad idea.
It's expensive support wise, but you could run different h/w and
bind at two locations. This is perfectly acceptable operationally,
AFAIK. Security is another story. That depends largely on people these
days so YMMV.

Anyhow, does anyone know what really happened?
