...system, 16 years ago, they'd let us schedule software
upgrades for Mon night, between 02:00 and 06:00. Tuesday, and then
Thursday, were second and third choice - that's when there were the least
number of calls. And allow me to venture to suggest that life-or-death
calls to a 911 ctr (the calltakers went back to cards during that time)
wasn't more important than world-wide business....
