This thread was referring to my custom VPS where I'm hosting the cixsquad.com website. I moved it over to a Digital Ocean droplet and setup the hosting environment from scratch. I got sick of dealing with the Plesk crap on my other VPS. I don't trust my *nix knowledge enough to ever use a VPS I setup myself from scratch in a production environment, since I'm sure there's major security vulnerabilities I've overlooked (I'm not an experienced *nix administrator - it simply isn't my specialty). But this VPS is perfect for casual stuff like CiX, some brochure websites I'm hosting for friends and family, personal projects, etc.
