It seems like this "company" is completely abandoned. Some their hosting services are completely down more than a week and no response, no explanation given. I try to to get in touch with them whole this time, but it seems impossible.
Their site is still up and so are some their servers most likely, but I suggest to all their customers which service is still online to make backups regulary because as it seems boxVPS ship is sinking.
Some week ago I also contacted their representative budman714 on WHT, I see his posts from yesterday here but so far.. no response on my private inquiry regarding this long service downtime and high priority ticket ignorance (it's more than a week!).
BoxVPS clients which are still lucky to have their datas online.. just make backups!
