Nothing formal, but if the service itself does go down (i.e. your VPS drops and can't be restarted due to a service problem, or connectivity fails, etc.) refund

Nothing formal, but if the service itself does go down (i.e. your VPS drops and can't be restarted due to a service problem, or connectivity fails, etc.) refunds / service credits would be issued. We really haven't encountered this enough to have a formal policy as of yet -- the redundancies we use are quite good.
