Satellite Views Of The Blackout

An anonymous reader writes "These Before and After satellite views of the blackout, from the NOAA, show the geographic extent and intensity of the outage. Toronto, Ottawa, and Detroit seem the worst hit. Currently, a cnn article mentions that a reverse of power flow around Lake Erie may have caused an overload that triggered the programmed shutdown of the power grid. Would be interesting to know how the system and software works, but then again, that information could be dangerous in the wrong hands."

Dangerous in the wrong hands?

[bc90021]

If a private citizen were to show the interconnections of the power grid on their website, what would happen? How long would it be before the government ordered him/her to remove that information in the interest of "National Security"? Why is it that CNN can show it freely? A similar map was being broadcast on TV all morning.

And as for how the software works, it would be interesting to know just what OS the power company computers were running. Not to sound like a conspiracy theorist (well, ok, that's exactly what I'm trying to sound like ;) ) as soon as there were variants on the Blaster worm, a large section of the power went out? Hhhmmm...

Some people on bugtraq are already speculating that the blaster worm may have had something to do with it...

Got me if it's true. I'm not up on that stuff. Made for some interesting reading though! :)

How many died in this, the biggest outage in the US for decades? A half-dozen.

You don't target the plants. You hit the high-voltage transformers. They step down the power from the high-voltage long-distance power lines to the local transmission lines. There's only ~3000 in the whole United States. They're not made domestically and there's an 18 month lead time on manufacture.

You pick a municipality, e.g. New York. You get ~20 men, armed with automatic weapons and explosives. They start ~1am, and go around taking out HVTs. You have four groups; the first two hits each group makes (maybe more) meet no resistance at all, there's no security on these things beyond a padlocked gate.

By the time people realize that a coordinated attack is going on, and get armed guards capable of fighting off automatic weapons placed around the remaining HVTs, at least 30 of them are down. Restoring power takes weeks, possibly a couple of months. Imagine what that'd do to, e.g., Wall Street.

Now, imagine one of those four groups, instead of targeting HVTs, targets water mains instead. You now have a very large region without power or water. That requires a massive support effort, possibly even refugee camps. Picture the economic impact.

Pick two widely separated regions (e.g. New York and, I dunno, Dallas, Texas (they're even more dependent on water and power for survival there than most)) and you halve the damage to each one but more than double the chaos.

The only weird thing is why something like this hasn't happened yet.
