I suggest that causing a cascade effect and increasing the area of an outage isn't a good way to design a system.
I would agree, that is why I am worried about year 2K power issues. I think for the most part everything is ok with most of the larger providers, but I have talked to several smaller energy providers who will not be ready for y2k. The systems that may/will (depending on who you talk to) fail are normally not that big of a deal to restart after they trip. The problem is that this could cause a cascading failure that would take down most of the national grid. When you have something like that happen it is not that easy to bring everything back on-line. As far as I know we have never had the entire national grid fail, we have had large sections (say New York, 13 north western states, etc.) of the grid fail because of cascading failures that were caused by very small problems. If you are a ISP, you better have your generators ready, I think you are going to need to use them. -- Check out the new CLEC mailing list at http://www.robotics.net/clec
