Why don't some websites allow access to the homepage? (In other words, there is no button on the home page)

Question

I was just browsing Five Star Library (you know, looking for answers to textbooks), and there was no home button. I thought it was strange. Then I clicked on a category and saw the word home page. However, when I clicked on the home page, it showed 403. Why?

Answer 1

His website is down or under maintenance
