FWSS website is now hosted on VPS.NET's cloud vps. Due to some technical obstacles the website was unavailable for couple of days ( my sincere apology ).
The server consists of 1 node only ( I'll be adding nodes soon ). OS: CentOS 5.5/64, CPU: 0.6GHz, RAM: 376MB, Storage: 10GB, Bandwidth: 250GB. As you can see this is a very minimalistic configuration, however, hosting 5 WordPress websites in 2 domains it still performs better than one WordPress website in shared hosting environment.
In near future the server will have at least 4 nodes hosting 13 websites in 7 domains.
If you would like me to share my experience with VPS.NET or you have technical questions regarding vps configuration, please leave a comment here.
