I have around 15 web sites, 5 forums, over 200K register users in 3 hosting companies and I'm getting tires of unreliable web hosting. I'm thinking on getting a dedicated server on a xx company (that promise 100 uptime), but the difference between the share hosting and the dedicated server is big. The hosting service cost will jump from 4% to about 12% of my income.

My question

Is it worthed to make the change?

Does having a fast and reliable hosting makes a difference on users experience?

Can I gain more users if the server is fast and reliable?

I would really appreciate if you provided your opinion
