"managed hosting" means different things to different hosts. I see lots of hosts claim to be managed but then give you a CPanel, which to me means you're still doing quite a bit of the management.
Other hosts, similar to us, do everything for you. We, in essence, become your personal system administrators and do everything for you except build your site. We manage backups, monitoring, and handle any request you have, from adding domains to installing complicated programs, setting up clusters, load balancing, etc - whatever it is you need. That is "managed" if you ask me
Feel free to hit us up at sales AT nationalnet DOT com if you have further questions or if we can do anything for you.
