Inadequate situational awareness at FirstEnergy
The fault alarm The primary cause of the loss of situational awareness was failure of the fault alarm part of a computer system. The operators noticed and switched to another system but that also failed a few minutes later. Attempts to restore service failed until the main system, its backup and all connected systems were restarted after the blackout.
Loss awareness of the state of their network First Energy operators, in part due to failure of the computer system which should have alerted them to failures in their transmission system and failure to sufficiently trim trees under its power lines in part of its Ohio service area, which led to normal heat-caused sagging of power lines operating within their capacity limits to touch the trees and go out of service. These problems were compounded, but not caused, by the Eastlake 5 power plant near Cleveland, Ohio going offline and causing an increase in the need to transfer power over the lines. It also found that FirstEnergy did not warn other control centers until it was too late because of faulty monitoring equipment and inadequate staff. The cascading effect that resulted ultimately forced the shutdown of more than 100 power plants.
Someone moved this page to Northeast North America blackout of 2003 with an edit summary, "not the only place in the world to have power cuts". Though that may be true, this article is specifically about the blackout that occured in the Northeast of the American continent in 2003 (clue is in the title). Also, "Northeast North" does not make sense as it is not a recognised compass point. Moved back to where it was. DieSwartzPunkt (talk) 07:26, 26 June 2014 (UTC)
i agree that "Northeast North" does not make sense. It should be "Northeastern North", like western West Virginia. Not west West Virginia. But User:Simply south has already changed it back without discussion here. Ill advised. — TimL • talk 22:51, 26 June 2014 (UTC)

I'm in hearty agreement with those who object to constructions on the basis of "Northeast of what". My own pet peeve is describing an accent as "Mid Atlantic" . At first I thought it meant half US, half South British English. — Preceding unsigned comment added by DaveyHume (talk • contribs) 15:59, 28 October 2014 (UTC)
Anyone conversant enough with computer software to recognise the name Unix should know that the software failure had nothing to do with the fact that it was running on Unix. Would Wikipedia report a bandit software "denial of service" as a Windows and Microsoft Office attack? Most such offences are in fact facilitated by weaknesses in that software, aggravated by the failure to use certain elementary precautions like not oening attachments from untrustworthy (most) sources.DaveyHume (talk) 15:49, 28 October 2014 (UTC)
