Unnamed Administration sources reported that Roeland M.J. Meyer said:Are there things that can happen to both which will really ruin your day?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. ___________________________________________________ Roeland M.J.
