Known host provide good service and support but i miss one think it's called ddos protection. Now a day ddos is a very common issue. known host not provide ddos protection. I see other provider provide it, I hope they will start it very soon.
@whmsys - I disagree. It really depends on what DDOS I'm sure, but I run some pretty big sites that have gotten hit before when I was with limestone networks (another great company but I wanted a managed service which is why I switched). Since I've switched I've never seen more than a few minutes of downtime. They do an outstanding job protecting against DDOS attacks. When you get a VPS from them it comes pre hardened with some software packages that I didn't know you could integrate with cpanel, but that have done wonders in protecting from random attacks usually from russia, china, etc. So they may not advertise it, but your certainly get it.
@LuxuryServers - I've been with them for 9 months now.
