I rented the 4gb ram VPS for a full year and have only been down once and that was due to a datacenter migration and it was done very late at night (and scheduled 4 nights ahead of time). Use my referral if you do sign up

(coupon code:
vnc).
FWIW, I completely ran a webhost several years ago, I was the sole operator of the helpdesk and split server related responsibilities with the company owner; it's really not that difficult once everything is configured. 35 servers, one of which was for a high scale CMS system's site and dev platform.
If there are any service related questions you have that I can help you with, just let me know...
