Website continuously gets "reverted"?

Joseph Stacklin · October 19, 2017

Hello, everyone. I don't even know how to start.

So something I do in my free time is host websites, but the server host I am with currently isn't 100% transparent about where they get their servers (but they are dirt cheap which is why I use them and I know: "You get what you pay for"). The issue I'm having is that my sites (and my clients sites) will suddenly revert anywhere from hours before to days before. Obviously daily backups are the answer here, however I don't know if this is an issue caused by me (especially since this is happening across many different servers all with the same exact programs minus one or two PHP plugins) or if it's the server host not being diligent enough to take an active backup and a passive backup before they mess with things on their end. I've reached out to them and they claim that there isn't any "tampering" being done and that "each server is the customer's only and they don't have access to it".

To be honest I don't even know, if it is my fault, what logs to upload so I can get help so here's my specs, just in case they will help (I know OpenVZ has issues here and there, but again it's the only option I have and I have never heard of such an issue with OVZ):

OpenVZ Containers running Ubuntu 16.04 with all latest security patches and updates
1-8GB RAM (varies on each server)
Varied Swap levels (20-50GB - SHHH.. I know it's a lot but I like my swap)
2-8 vCPU cores
mySQL, Apache2 (web server), Nginx (reverse proxy), Dovecot, Exim4, VSFTPd, IPTables, Fail2Ban, clamav, VestaCP (website management panel)

If anyone has any idea I would love to hear it. If you need any logs, please let me know. The sites affected go from simple one page HTML coded sites, to Wordpress packages, and even Drupal packages (all obviously separated vHosts). I'm honestly stumped. The logs could show a time discrepancy when it happens, but because I manage so many sites it's hard for me to know EXACTLY when it happens so I can check the log for the time jumps.
