[Foxfire]

I would like to host 10 huge traffic web sites and need reliable host with responsive customer support.
USA:
Super fast processor, Up to 64GB RAM, Up to 8TB Storage
What can you say about HostingSource.com , Wiredtree.com and Cloudarion.com dedicated web hosting services?
What host is better from your views?

Hostingsource.com is rated at the top of my list for a satisfying experience. Recommended these professionals to others.
The techs contact me checking to see if I have any issues just to be on the safe side.
Good job!

The price is very reasonable compared to other hosts I've seen. Save Big on Hosting - 50% off 1st month on all HostingSource.com Servers/VPS plans.

Give my vote for HostingSource.com high end servers. The support is the best I've ever had on a shared server. I love the fact that I feel like a valued client whenever I have a question that I need to ask - it feels like I'm in contact with human beings who treat me as a human being, rather than getting soulless cranky responses.

How fast would you say the customer service is? When you have an issue how fast is it generally repaired?
