it just dawned on me, watching the news coverage of the Canooks and us bickering
about who 'started it'. maybe _no_one_ wants to admit that some part of this
grid was under control of WinTel platforms?(!)

it's really just a coincidence that this 'worm' took down some networks
starting on Monday, right? --Loren

(ahem)

"Canooks"?

Canook +blackout = Canooky (?) ;-)

We will find out in 9 months..eh?


"There were fluctuations hours before the failure" . Sounds like a
positive feedback effect caused the problem .

e.g. so many control systems trying to compensate for the original
glitch, due to the sheer size of the grid it began oscillating at a
low frequency which built up and finally caused a system failure .

Recall Tahoma Narrows bridge . Wind was just at the wrong speed to
induce resonance .

Perhaps a seismic event caused it ? Something caused a slow build-up
(perhaps current was being drawn in the right pattern + some other
event) causing the above scenario a couple of hours later .
