well one would think that they could at least get power redundancy right...
It is very similar to suggesting redundancy within a site against building collapse. Reliable power redundancy is very hard and very expensive. Much harder and much more expensive than achieving network redunancy against switch or router failures. And there are always tradeoffs involved, because there is only one utility grid available. There are always some limitations in the amount of isolation possible. You have devices plugged into both power systems. There is some possibility a random device plugged into both systems creates a short in both branches that it plugs into. Both power systems always have to share the same ground, due to safety considerations. Both power systems always have to have fuses or breakers installed, due to safety considerations, and there is always a possibility that various kinds of anomolies cause fuses to simultaneously blow in both systems. -- -JH
