I didn't realize the message appended below had reached only the info mailing list,
not gnuplot-beta.

If anyone here understands how any of this works or how to fix it,
please speak up! 

I tried to forward it to the last Email address I had for Clark Gaylord
but it bounced.

Problem with gnuplot.info website on IPv6

Hi all,

It appears that the A and AAAA DNS records for "www.gnuplot.info" are
pointing to completely different webservers.

The server that's answering IPv4 requests seems to be up-to-date, with
information about Gnuplot 6.0. It reports a Server header of "nginx", and a
Last-Modified date for the front page of December 29, 2023.

The server that's answering IPv6 requests, on the other hand, is
substantially out-of-date. The front page shows Gnuplot 5.4 as the latest
release, with a Last-Modified date of October 2, 2022. New pages such as
http://www.gnuplot.info/ReleaseNotes_6_0_0.html all return 404 errors. The
server also reports its version as Apache 2.2.17, which is from 2010.

This affects everyone with a working IPv6 setup. If it's not possible to
find and update the server that's serving the v6 traffic, then I think it
would be best to remove the AAAA DNS record so that everyone can see the
updated version of the site. v6 support isn't just limited to a few people
anymore.

Thanks,

Andrew
