This reminds me of a passage from Bruce Sterling's _The Hacker Crackdown_. Parked outside the back is a power-generation truck. The generator strikes me as rather anomalous. Don't they already have their own generators in this eight-story monster? Then the suspicion strikes me that NYNEX must have heard of the September 17 AT&T power-outage which crashed New York City. Belt-and-suspenders, this generator. Very telco. michael
