I went through the same mess during the last ten days too, including a considerable loss of data (not a big problem, if you have backups).
However, now everything is working fine – and pretty a lot faster than before.
It's obvious to me, that the x10hosting folks are working hardly on their servers currently. That's inevitable from time to time with any hoster.
Unfortunately there is no information about it. Neither in twitter (last post of 2016) nor in facebook, nor in the blog.
So the main problem seems to be their policy of communication.
