This blog's non-mobile version wasn't online for at least the last few minutes.
http://verteidigung-und-freiheit.blogspot.com/ was unaffected.
I have no idea what happened, and nothing helped though everything pointed at a corrupted template.
The blog miraculously re-appeared without the template changes I made when trying to revive it. I suppose blogger/blogspot had issues and used a backup to solve them.
