FWIW, I tried connecting to 100+ NASA web servers using the same Perl
(5.6.1) and Solaris box that triggered this report, no dice. Even if
that DNS address were still around I doubt it would help as it must have
something to do with the type of httpd they were running and I imagine
that even they would have upgraded it in 11 years.

Gosh. You still have both! I had assumed that both hosts were long gone.

Shame that they don't have their end still. Thanks for trying.

I'm suspicious that it was an OS bug. The SIGPIPE arriving when it did was
completely illogical.
