Yupapa, you are acting as if this is news to you when in fact many people have been trying to warn you about donhost for months! If you have any respect for your customers I would take your clients elsewhere, be it dedicated, or another more reliable reseller ( My suggestion from excellent experience would be VenturesOnline.com ). Im not trying to put you down I just don't want to see you end up like 9kd or tacidhost ( yeah people there is more to the tacid story I realise that ). Many people have have invested there hard earned dollars in your service and you should do your best to provide a decent service, other than the obviously over packed servers that donhost offer. I have heard nothing but bad about this company, and if you stay much longer you will be in the same boat as them. Don't let it happen to you, please!
BTW, what they mean by "You are not financially interesting for us" is that they are using to many resources on the machines and donhost cant afford to host them any longer. Obviously because there reseller plan lacks proper structure.
