At least it wasn't  a "totally transparent"  UPS test scheduled for the
Thursday of Thanksgiving weekend.  My personal philosophy is that every rack
should have its own UPS separate from the data center one, with enough
capacity to keep going through blips,and handle a clean shutdown if
necessary.  That way,  when the ops team messes up, far fewer sysadmins get
their weekend ruined.

Of course, the real problem is that too many people are writing unoptimized
code in energy-inefficient languages like ruby and PHP, which require far
more servers, and far more cooling, to do the same work as properly written
code.  If carbon emissions should turn out to be a  strong forcer  of global
warming, then we can clearly say that every time you write  PHP, Phil Jones
kills a polar bear. Please, think of the polar bears.
