As Mouse says, this site isn't sending a Content-Type header. Lynx
actually has an option for this, and so if Lynxes are treating
it differently it probably means the option differs between
environments.
Extract from lynx.cfg:
.h2 PREFERRED_CONTENT_TYPE
# When doing a GET, lynx expects the server to provide a Content-Type, i.e.,
# the MIME name which tells it how to present data. When that is missing
# lynx uses this value.
#PREFERRED_CONTENT_TYPE: text/plain
You can set this within Lynx on the (o)ptions screen, though by default
it's not saved to disk. You want to set it to text/html in order to
properly view the above page.
