What is inaccessible about a bunch of text on a page? It's readable in any kind of viewer you want, and a screen reader or a braille display can parse it. Does "accessibility" now mean that you have to have a navbar at the top of the screen for some reason?
The fact that almost every single link on the page goes to a 404, times out, or says Forbidden, might have something to do with it.
Or the gigantic, seemingly meaningless URL.
I don't know what this page is, but it doesn't seem to exist in any kind of context of a larger website. How did anybody even find this in the first place?
"Accessible," like so many words, means different things to different people.
You're saying this page seems inaccessible: how did anyone find this page? How is a person meant to access this stranded corner of the web?
They're saying this page has good accessibility: those with impaired vision, who use text to speech tools and the like, would not face difficulty with this simple HTML.
Looking closer at the URL, I realize now it has "2002_09_10" in the path. Presumably it was created then and hasn't been fully rewritten since, so while not quite 25 years old, it seems that might be the reason it doesn't have any recent accessibility features.
