Some piracy anime streaming websites, such as Aniwave (aka 9anime) shut down.
It seems animesuge.to, anix.to and aniwave.to closed down with the exact same message, though there may be a few other sites that closed down in a similar way.
You should bookmark theindex.moe (aka piracy.moe), it has a comprehensive list of manga/anime streaming sites, you can use search criteria like langauges, soft-subs, noads, no anti-adblock, etc.
That's a real bummer. I've always had a hard time surfing the high seas for anime since I mostly watch dubbed. I've found alternative sites but they seem to have worse browsing especially for dubs.
