The: http://lynx.isc.org/ is not loading.
Is it the https://lynx.invisible-island.net/ what is the official for the "lynx", the text-based webbrowser?
The homepage for Lynx has moved more than once, as discussed in this development page:
However, things change. Paul Vixie left ISC in mid-2013 to form a new company. At the time, that did not affect Lynx—from ISC's standpoint Lynx was just a box in a rack of servers. For the last four years of Lynx's stay at ISC, I did all of the software maintenance for the project. Still, a box in a rack costs money for electricity. Late in 2015, ISC shifted away from this style of project support, to reduce costs. I expanded my website to incorporate Lynx (roughly doubling the size of the site).
This new site is still the current homepage as of February 2018.
http://lynx.invisible-island.net/ is the current official home page for the Lynx text-based web browser.
The move is mentioned in the
CHANGES document for release "2.8.9dev.7" in December 2015:
* move homepage for Lynx from http://lynx.isc.org to http://lynx.invisible-island.net because ISC has ended support -TD
