The addresses went dark, the name did not
"what happened to animeflix", "is animeflix shut down", "did animeflix get taken down", "animeflix shutdown", "is animeflix back" and "animeflix new domain" come up wherever the name is known. The short answer is that addresses under the name have gone dark more than once, as addresses do, and each time people searched for the new one. This address is the site rebuilt, pointing through Watch now at the licensed services carrying each anime in your country, and it is the one to keep.
Is it down right now
If this address will not load, switch the phone between Wi-Fi and mobile data, because a filtering network is the usual cause; the not working page goes through every case. If you came from an old suffix, the addresses page lists them.
What stayed
The design people remember, the menu, the ribbons, the Hindi-first shelves, and the thing the name is searched for: the anime, every season, every episode, and where it plays.
