    Its highly unlikely that msblast had anything to do with the power outage.
    For one, the internal rpc network that is used to monitor actual power
    spikes, and to move current from one circut to the next in a grid is a
    closed network. And in the areas were it cant be closed (between major
    utilities) it is tunnled via a VPN. Yes it runs a bit of NT4 and a bit of
    Windows 2000, In the next few years there has been a plan proposed to make
    freeBSD a standard.

    MSblast did not cause this, there have been warnings for the last 10 years
    that the grid was overloaded in the particular ring were the overload
    started. For years people have been warning that if a major transmitton line
    went during a high demand period of time, then you could be looking at a
    surge larger than can be midigated coming out of that ring. And then when it
    happens people come up with this theory that its msblast? Please, if that
    were the case, why have none of hte other billons of windows vunerabilities
    ever affected the grid? more specifically, why havent any of the thousands
    of rpc vunerabilites ever effected the grid?

    And sure enough, this morning on CNN, officals said they have a working
    theory that a major transmition line inside the ring went, wich created a
    back wave in the grid until it finaly came around in the form of a hudge
    surge. Niagra somehow saw this coming and shut down all generators in time
    to stay on the grid, and as the failure expanded more failsafes kicked in to
    contain it.

    This is far from a complete explanation. But it fits the avialable facts, it
    fits the timetable of what happened, and it makes logical sense in relation
    to the recent history of the power grid.

    Now can we give msblast a rest? :)
