Stable Server Located in Thailand?
 

My current host started to make me nervous because of bad customer support and downtime.
Most of my clients are located in Thailand. I need stable server with 500 gbs of SSD space, 16 gbs of RAM and 5000 gbs of bandwidth.
Well, XXI Web Hosting was recommended to me as a good option. What can you say about them? need feedbacks. Also any alternatives?

Thanks in advance.

As far as I know servers from a particular location can be expensive. Some good US based provider with good network providers will be a better idea. If you check kvchosting.net or cloudarion.com you might better deals in terms of the price while connection speed will be the same.
