Kalthoff...did you manage to sort this issue out yet? Just discovered one of my sites having the EXACT same issue as yours. Done all the checks as suggested and my root domain doesn't show in the serps, a snippet of content brings up nothing from my site (and nothing that looks hijacked either). The only thing reflecting is a sub, which somehow we are ranking # 1 with on our major phrase (the page is actually nothing but a query form with meta tags). It's wierd, 7th of December it was there and 9th of Jan its gone! Along with that we fell off the serps for some of our phrases...and I mean FELL OFF! We have made zero changes and http response is 200 (ok). Did you manage to find a solution?
