Nobody knows 100% yet however I've been checking the site every few hours since it went down, and from what I've seen and know about kissanime's history and from what others have also posted it's safe to assume the site WILL be coming back.
The site has gone down many times in the past for various reasons dealing with the sites internals. They were once down for a few days like this when they were changing to new hosts. The site going down is nothing new, although yes this time it is a bit different.
The last kiss-specific error that we saw said that kiss was going to be down for a while while they upgrade their backend. This is most likely the case since incidents like this HAVE happens to kiss before, like the time I mentioned when they changed hosts.
Since this is obviously a much bigger change (changing the whole backend is no small task, and is much larger a job than simply changing hosts) it will of course take longer to finish, even though the original error said 24 hours.
In case you didn't know, the site WAS up and running yesterday (or maybe the day before, forgot which) however you could see any content. It was just a white screen, but you were able to connect perfectly fine. This was most likely some kind of test for the new backend. One person made a post theorizing that the content was available but only to specific test users, which makes sense.
As an alternative until kiss is back up, I recommend 9anime. The site is much cleaner than kiss (in my opinion), has all the same features, same series collection both sub and dub, full HD, you can download all the series, changing episodes doesn't require changing pages, there is virtually 0 load time for episodes and it's all free http://9anime.to/
I just recently discovered http://9anime.to/ Its pretty solid, has a decent player, no ads to begin with and they are pretty fast at adding stuff if you request it. I requested ZetMan and they got it on there the next day. They have a pretty solid selection now and it has been growing fast.
I'm not as learned as some of the other fans here but I'll try my best. If you have more specific questions about what you want explained that might help me make things clearer.
I think after the point you're talking about witch-Homura's labyrinth expanded until it contained the entire universe, "re-writing" it again. Sayaka is the only one who remembers what she is. Not sure what's confusing you about Bebe. She's the witch that decapitated Mami before she became a witch, and just like the other girls she's there because she's assisting Goddess Madoka, however that works.
The concept movie is four minutes long and will serve as the "core and trailer of a new Madoka Magica project." You can watch it here. and read the transcript here.
9anime is your best friend. High quality, downloadable episodes, will upload anime you request very quickly (I asked for Ruin Explorers and all episodes were up the very next day), and best of all, no ads. Solid site, check it out. http://9anime.to/
Refer to this post. They're switching CDNs (content delivery network) so none of the content is available right now.
My recommendation for alternative sites is 9anime or AnimeDaisuki.
Not sure if they are exactly what you are looking for but I found these: Hoozuki no Reitetsu OVA: http://9anime.to/watch/hoozuki-no-reitetsu-ova.l4q6/ll97l3 Osomatsu: http://9anime.to/watch/osomatsu-san.80o/vwo86
Here in this reddit they are saying use it at your own risk ONLY for watching do not login/register so yeah but if you want an alternative for kissanime http://9anime.to/ or http://www.masterani.me/ or http://animehaven.to/ This is where im watching anime from right now. masterani.me doesn't have every single anime in the world but it does it job. Btw you can print your bookmark list from kissanime(when they fix it) so you can have a save. I already made a post about it so people know.You can check it out if you want.
Good luck! Just as a heads up, make sure to watch End of Evangelion after you finish the series. Otherwise the last two episodes make little sense.
After installing the filter list, instead of playing the video I get the notification
" Please open http://9anime.to on your browser to watch for free.
We don't allow to load our website in any other app. "
I disabled other blockers, and only ublocker is running for 9anime. Did the 'if it still doesn't work on ublock' section, and still only displays the notification. Not sure what else to do.
new episode, or new series?
if you didn't realise there was a new series, it's understandable that you'd miss it. As it's been licenced by amazon. Therefor CR, Horrible don't release it. You can find it on nyaa if you use the japanese name or stream from kiss or 9 if you'd prefer.
Tried almost every site that was posted here. I'm watching Super Doll Licca-chan recently. http://9anime.to has it but only the dub version... I'm missing KA more.
EDIT: Apparently it's still in the original Jap dubbing. YAY! Thank you for sharing these sites!
Since kiss went down I've been using 9anime as a backup. I'd highly recommend trying it. It has all the same features and series, dubbed and dubbed, that kiss has (had?) and you can download the episodes. Not to mention the 0 load time.
But yea 9 is probably your best bet. It's the closest one too kiss I've found (and tbh I kinda prefer 9 now) plus it lets you download the episodes, like you're looking for.
use 9anime, it doesn't have any pop-up ads or malware, but if it does, i wouldnt get an account for the site. i'm a vine editor and use kissanime to download episodes and 9anime is amazing to use since kissanime is down. sorry for all the rambling.
