I had my darkstar server for over 2 years. It was plagued by poor connection issues, and at one point they just "decommissioned" the machine my server was on without any warning, while it was in use.
I had cash in my account upon cancellation, and their policy is to not refund those funds. The company was short with me when I requested a refund and i was told that they would not give me that money back, basically stealing from me and hiding behind "Terms of Service" to justify that theft.
DO NOT DO BUSINESS WITH THIS COMPANY.
