Yes.

Actually, on 2Sep98, PacBell had a CO failure that knocked out service, in
Livermore, for 12 hours. Voice, data, everything, not even 911!

Not sure how a CO failure brings down leased line data....

The *whole* CO went off-line. 

What WILL bring down the whole house..:

      Fiber cut -- as well as other wholescale transmission
              FUBAR's.

That wouldn't have taken the entire town off-line.

      Power -- remember the NYC ATT crash? It took hours
              to bring the DACS back up... Don't
              overlook lightning strikes on the incoming power
              feed.

      Enviromental -- if the HVAC croaks, if a waterline floods
              from the cable vault on up, or there's an
              earthquake, or a Hinsdale-style fire. 

I would have notice an earthquake, of the fire. The CO's not far from here.

But such will never happen, so we can all rest easy....right?

Cascaded failures will do it. aka Murphy having a party.
