It was probably slow, as you say, but it turns out our machines were
powered off by one of the other guys in our group because the UPS was
draining fast. Power was lost because of a major storm on the central
California coast.
I have a feeling it was working but was interrupted. I'll try again
when power is restored...
Thanks so much for your input!
