Well, that depends. How do you define "top"? That seems like a very subjective criterion. A few options that come to mind: Softlayer OVH Kimsufi Hetzner
I really like web hosting solutions provided by citynetworkhosting.com. Their service is reliable, so I can name them one of the top hosts.
Are you want any specific technology based server or any server will good for you like Windows,java,Linux etc.?
It's impossible to tell you any good recommendations because your question is too vague. For example a good control panel (like CPanel, DirectAdmin, etc.) is often the basis for being easy to use. A great value depends on the features and resources you need. If you need suggestions which are really useful for you and not just in general: tell us your exactly needs.
I think this is the key. In general I would always go for servers hosted in Europe based on the audience the sites are targeting but this depends. The next question is do you expect a certain control panel or are able to deal with each of the industry standards besides cPanel.
Hi, I have been using cloudc.me for two years and have had no problems. I totally agree with Sensei.Design that european based web hosting providers are one of the best. Not only are they reliable but also provide high quality services like no others. My experience with cloudc.me has been a positive one so far. I moved from hostgator in the search for a web host with addition premium services. Cloudc.me provided me with dedicated servers as well as free DDOS protection with an additional 99.9% uptime guarantee. Also, the variety of minecraft-ready dedicated servers are a bonus. Don't take my word for it, you might want to give them a try to see for yourself as I am sharing my experience with them.
