Hosting Reality Check Network hacked

Today the hosting of the Reality Check Network ( AS46652 ) was hacked.

At the moment, all sites are. Hosting was known for hosting several very large adult and torrent (including torrents.net) sites. According to the hosting representatives, the operating systems on all servers are damaged and now preparations are underway to restore all the servers from the backup.

Hacking is interesting because the attacker hacked the hosting network and gained access to the servers (apparently all), damaging their operating systems. The only way out is to format all the servers and restore data from the backup.

The first time I hear about this type of hacking hosting.
