Fixable.  UPS + AC/DC Power generators.

Um, you ought to know better than to put your damn equipment in a building
that's going to get destroyed by a tornado, I guess.  ;-)

Seriously, though.   "Acts of God" as they are called are typically not
counted either.  When it comes right down to it, if the customer no longer 
has a premise, then they are probably less worried about their equipment
being up and operational.  Technically, it only matters if you define your
network as extending up to, and perhaps beyond CPE, or if it is just before
CPE, or even futher, if it ends right at the Bell Demark at your POP.

Since RTD purchases all the circuits for clients, our network (read, area of
responsibility) includes everything up to the CPE, but not CPE itself.  If
there are circuit's down to individual clients as a result of Bell, we don't
count it as downtime, even though it is logged and pursued as any other outage.

As for connectivity to the rest of the 'net, it's *really* subjective.  We
sort of consider 50%+ of estimated Internet connectivity "up," even though
we probably shouldn't.  Internet connectivity uptime can be increased simply
by adding more links to NSP's, so you can't just throw responsibility for that
entirely onto your provider.

Why do I believe that?  hehe.
