which is where i got this quote:
"......This power supplier is specified as a reference customer of Northern Dynamics. This company calls itself as "Home OF the OPC Experts" and offers a set of products, which use OPC for communication with control and control systems. OPC stands for Process control "for" OLE for and touches down on Microsofts COM/DCOM model. That is however exactly the technology with the safety hole, which the worm W32.Blaster uses. In a net, in which this worm is active, malfunctioned due to the regular restarts, which observe now final users also concerned with their PCS, DCOM communication and concomitantly OPC on ungepatchten systems."
=========================================================
the blackout could have started with lightning or a fallen tree limb. that would have caused a local outage. but in a system with circuit breakers everywhere, it would not have spread to be such a large regional outage.
