Is Zollner Illusion still up?
Yes. We load every site in this catalogue in a real browser rather than trusting a status code, because a page can answer 200 OK and still be a parked domain or an empty frame. Zollner Illusion passed that check on August 28, 2026. Anything that stops loading, or starts refusing to be embedded, is removed from the catalogue rather than left to disappoint someone.
