Error 404 · Apolo 8
Bis hierher haben wir es geschafft. Die Seite nicht.
Vom Mond aus sieht man die ganze Erde, aber diese Adresse taucht nirgends auf.

Mehr aus 404
Wofür du ihn nutzen kannst
Auf einer 404-Seite landet man öfter, als man denkt: ein alter Link im Newsletter, ein Tippfehler, eine Seite, die nach dem Relaunch umgezogen ist. Diese Earthrise-Szene macht aus dem Moment etwas Ruhiges. Sie passt zu einem Reisebüro, einem Wissenschaftsmuseum oder einem Umweltprojekt, das eine eigene 404-Fehlerseite im Look der Marke möchte.
Du kannst die 404.html einfach so einfügen oder das Blau anpassen und das Tempo senken, wenn es ruhiger wirken soll. Halte den Button-Text kurz, etwa „Zurück nach Hause“, damit niemand überlegen muss, wohin es weitergeht.
