GlowHost.com provides different dedicated servers. I don't know which one to choose - fully managed dedicated servers and unmanaged dedis.
I have some experience in running dedis but I'm not sure I'll succeed in that. I wonder if it's possible to buy some hours of support from them in case of having some issues.

If you have enough experience, go with an unmanaged dedi from Glowhost.com. They are cheaper with many resourceful features. As for fully managed - they are good if you have neither time nor inclination to manage them.

In any case facing some issues you may pay for the support to glowhost.com support, I think they won't refuse their clients. You may ask them about these thing directly using their ticket submission.

Have also a look at ServerPoint.com - this company has something to suit your requirements, if glowhost does, serverpoint will surely be OK. Moreover they are very reputable provider with various options to choose from.

There is no denying the fact that comes out of a comparison. I advise you to look at A2hosting.com, as this company is really flexible and stable. If you hurry up, you will get a chance to save 15% off new purchases! Use code sitelaunch2 at checkout.

A dedi from Glowhost.com in any case is a good bet as this company has the reputation of a reliable company with rock-solid services and 24\7 support staff.

Hm ... Glowhost.com is a big hosting company with multifaceted services at affordable rate. They have many awards for their services and positive reviews.
They seem one of the most reliable companies for me.
