Didn't know that. Traceroute does seem somewhat more civilized with a
'-z 1' option. Useful knowledge. Thanks...

According to the ISP, the problem was a mildly misconfigured router
somewhere in Denver, CO. Seems to be all better now.

Yeah, I know. But it wasn't a matter of resending on error, it was that
the SSL handshake was taking longer than their web server considered
reasonable, so it quit waiting.

The Internet isn't as patient now as it was back in the dialup days.
Good thing, too, or I'd never have seen that there was a problem.

Thanks, list, for the replies to a confused admin :-)
