Been using
Liquid Web VPS and Servers for years for non-adult and adult projects. Fully Managed and I haven't had a minute of downtime as they monitor it and I also use a 1 minute monitor on my own as a backup. They host one of the biggest web hosting forums as well. May be more expensive than some others but you get what you pay for. Go Daddy is good for domains and SSL but for hosting I would stay away as any hosting that is dirt cheap is overloaded with users or they charge crazy prices for management.
