Re: Whooda belived this?

Don't know how relevant this is, but our only--ONLY--surprise system-down
outage, here since Nov. 1995 was when a power-backup electrician doing
maintenance threw a switch to put the 400 on straight power grid, and
everything went down, he said because it was wired wrong. Then I remembered
how the previous guy insisted on us bringing the system down first,
precisely because sometimes it is.

Score: Human cause-1; AS400 cause-0.

Now take our W-98 history...please...take it...away...
