RoseHosting has provided excellent VPS hosting services since the first day that I switched to their platform. My previous host was plagued with frequent hardware failures, server downtime, poor bandwidth and the inability to create backups correctly. RoseHosting has never once suffered from any of those problems. In addition, the one or two times that I've had to contact support, they have always responded quickly and resolved any issues as fast as can be expected.
Setup is quick, tech support is excellent, and you can have as much power and flexibility as you need.
