powerful managed servers?

[Querrido]

What are web hosting providers with powerful managed servers?
I need dedicated server hosting with 1000 gbs of Hard Disk + 24 GB - RAM + 18 TB - bandwidth
I know my several friends are happy using Okayservers.com and Centohost.com service - What is better? why?
What are your suggestions for the list?

Without a doubt, the best thing about Okayservers.com is their support - they are friendly and technically knowledgeable.
I've never came across another company that's provided such high quality and friendly help for my products, and also things not directly related to my service; they'll help you if they can.

Okayservers.com web host is fantastic host with great people and would not hesitate to recommend them.
I've noticed no downtime and my site loads faster than ever. Reliability is 100% I honestly cannot remember the last downtime my site has had.

The fact is, QHoster.com has some of the best customer support I've ever encountered.
They're honest, fast, and thorough; in fact, I never waited more than an hour, even when submitting support tickets at 3 or 4 in the morning on a weekend. They've provided more than what I need.

Highly recommend Centohost.com service for any kind of web sites.
Customer Support has addressed my few and minor requests immediately and professionally.
Reliability has exceeded my expectations.
